cmake: move modules into the "cmake/" top level dir
Our custom CMake module currently live in "cmake/Modules". As the
"cmake/" directory doesn't contain anything except the "Modules"
directory, it doesn't really make sense to have the additional
intermediate directory. So let's instead move the modules one level up
into the "cmake/" top level directory.

cmake: Sort source files for reproducible builds
We currently use `FILE(GLOB ...)` in most places to find source and
header files. This is problematic in that the order of files returned
depends on the operating system's directory iteration order and may thus
not be deterministic. As a result, we link object files in unspecified
order, which may cause the linker to emit different code across runs.
Fix this issue by sorting all code used as input to the libgit2 library
to improve the reliability of reproducible builds.

cmake: streamline backend detection
We're currently doing unnecessary work to auto-detect backends even if
the functionality is disabled altogether. Let's fix this by removing the
extraneous FOO_BACKEND variables, instead letting auto-detection modify
the variable itself.

cmake: use install directories provided via GNUInstallDirs
We currently hand-code logic to configure where to install our artifacts
via the `LIB_INSTALL_DIR`, `INCLUDE_INSTALL_DIR` and `BIN_INSTALL_DIR`
variables. This is reinventing the wheel, as CMake already provide a way
to do that via `CMAKE_INSTALL_<DIR>` paths, e.g. `CMAKE_INSTALL_LIB`.
This requires users of libgit2 to know about the discrepancy and will
require special hacks for any build systems that handle these variables
in an automated way. One such example is Gentoo Linux, which sets up
these paths in both the cmake and cmake-utils eclass.
So let's stop doing that: the GNUInstallDirs module handles it in a
better way for us, especially so as the actual values are dependent on
CMAKE_INSTALL_PREFIX. This commit removes our own set of variables and
instead refers users to use the standard ones.
As a second benefit, this commit also fixes our pkgconfig generation to
use the GNUInstallDirs module. We had a bug there where we ignored the
CMAKE_INSTALL_PREFIX when configuring the libdir and includedir keys, so
if libdir was set to "lib64", then libdir would be an invalid path. With
GNUInstallDirs, we can now use `CMAKE_INSTALL_FULL_LIBDIR`, which
handles the prefix for us.

cmake: sanitize boolean options passed by user
Starting with our conversions to mix backend-autodetection and selection
into a single variable (USE_GSSAPI, USE_HTTPS, USE_SHA1), we have
introduced a simple STREQUAL to check for "ON", which indicates that the
user wants us to auto-detect available backends and pick any one that's
available. This behaviour deviates from previous behaviour, as passing a
value like "yes", "on" or "true" will in fact be treated like a backend
name and result in autodetection failure.
Fix the issue by introducing a new function `SanitizeBool`. Given a
variable that may hold a boolean value, the function will sanitize that
variable to hold either "ON" or "OFF". In case it is not a recognized
boolean, we will just keep the value as-is. This fixes the above
described issue.

cmake: correct the link stanza for CoreFoundation
LIBRARIES is the (absolute?) path to the library.
LDFLAGS is the full linker stanza to correctly link with this lib.
By passing LIBRARIES as LIBGIT_LIBS, the linker ends up with the
absolute path for the SDK'ed version of CoreFoundation (which doesn't
exist), instead of the familiar `-framework CoreFoundation`.

cmake: fix various misuses of MESSAGE()
The MESSAGE() function expects as first argument the message type, e.g.
STATUS or FATAL_ERROR. In some places, we were misusing this to either
not provide any type, which would then erroneously print the message to
standard error, or to use FATAL instead of FATAL_ERROR.
Fix all of these instances. Also, remove some MESSAGE invocations that
are obvious leftovers from debugging the build system.

cmake: properly abort if no mbedTLS cert location is found
When using mbedTLS as backend, then the user may specify the location of
where system certificates are installed. If no such location is provided
by the user, CMake will try to autodetect the location by using the
openssl executable, if installed. If no location could be detected, then
the mbedTLS is essentially worthless as it is completely unable to
verify any certificates.
To avoid use of such misconfigured mbedTLS configurations, let's error
out if we were unable to find out the location.

cmake: include SHA1 headers into our source files
When selecting the SHA1 backend, we only include the respective C
implementation of the selected backend. But since commit bd48bf3fb
(hash: introduce source files to break include circles, 2019-06-14), we
have introduced separate headers and compilation units for all hashes.
So by not including the headers, we may not honor them to compute
whether a file needs to be recompiled and they also will not be
displayed in IDEs.
Add the header files to fix this problem.

hash: move SHA1 implementations into 'sha1/' folder
As we will include additional hash algorithms in the future due
to upstream git discussing a move away from SHA1, we should
accomodate for that and prepare for the move. As a first step,
move all SHA1 implementations into a common subdirectory.
Also, create a SHA1-specific header file that lives inside the
hash folder. This header will contain the SHA1-specific header
includes, function declarations and the SHA1 context structure.

win32: support upgrading warnings to errors (/WX)
For MSVC, support warnings as errors by providing the /WX compiler
flags. (/WX is the moral equivalent of -Werror.)
Disable warnings as errors ass part of xdiff, since it contains
warnings. But as a component of git itself, we want to avoid skew and
keep our implementation as similar as possible to theirs. We'll work
with upstream to fix these issues, but in the meantime, simply let those
continue to warn.

hash: introduce source files to break include circles
The hash source files have circular include dependencies right
now, which shows by our broken generic hash implementation. The
"hash.h" header declares two functions and the `git_hash_ctx`
typedef before actually including the hash backend header and can
only declare the remaining hash functions after the include due
to possibly static function declarations inside of the
implementation includes.
Let's break this cycle and help maintainability by creating a
real implementation file for each of the hash implementations.
Instead of relying on the exact include order, we now especially
avoid the use of `GIT_INLINE` for function declarations.

cmake: Modulize our TLS & hash detection
The interactions between `USE_HTTPS` and `SHA1_BACKEND` have been
streamlined. Previously we would have accepted not quite working
configurations (like, `-DUSE_HTTPS=OFF -DSHA1_BACKEND=OpenSSL`) and, as
the OpenSSL detection only ran with `USE_HTTPS`, the link would fail.
The detection was moved to a new `USE_SHA1`, modeled after `USE_HTTPS`,
which takes the values "CollisionDetection/Backend/Generic", to better
match how the "hashing backend" is selected, the default (ON) being
"CollisionDetection".
Note that, as `SHA1_BACKEND` is still used internally, you might need to
check what customization you're using it for.

Make ENABLE_WERROR actually work
This change explicitly adds -Werror to the CFLAGS.
Due to the way that the ADD_C_FLAG_IF_SUPPORTED() macro was mangling the
flag name to convert it into a define name, any warning that had a dash
in its name was not being correctly enabled. Additionally, any flag that
is enabled implicitly by the compiler (like -Wunused-result and
-Wdeprecated-declarations) would not cause an error unless they were
explicitly enabled with the ENABLE_WARNINGS() macro.

cmake: detect and use libc-provided iconv
While most systems provide a separate iconv library against which
applications can link, musl based systems do not provide such a library.
Instead, iconv functions are directly included in the C library. As our
current CMake module to locate the iconv library only checks whether a
library exists somewhere in the typical library directories, we will
never build libgit2 with libiconv support on such systems.
Extend the iconv module to also search whether libc provides iconv
functions, which we do by checking whether the `iconv_open` function
exists inside of libc. If this is the case, we will default to use the
libc provided one instead of trying to use a separate libiconv. While
this changes which iconv we use on systems where both libc and an
external libiconv exist, to the best of my knowledge common systems only
provide either one or the other.
Note that libiconv support in musl is held kind of basic. To quote musl
libc's page on functional differences from glibc [1]:
The iconv implementation musl is very small and oriented towards
being unobtrusive to static link. Its character set/encoding
coverage is very strong for its size, but not comprehensive like
glibc’s.
As we assume iconv to be a lot more capable than what musl provides,
some of our tests will fail if using iconv on musl-based platforms.

cmake: resolve libraries found by pkg-config
Libraries found by CMake modules are usually handled with their full
path. This makes linking against those libraries a lot more robust when
it comes to libraries in non-standard locations, as otherwise we might
mix up libraries from different locations when link directories are
given.
One excemption are libraries found by PKG_CHECK_MODULES. Instead of
returning libraries with their complete path, it will return the
variable names as well as a set of link directories. In case where
multiple sets of the same library are installed in different locations,
this can lead the compiler to link against the wrong libraries in the
end, when link directories of other dependencies are added.
To fix this shortcoming, we need to manually resolve library paths
returned by CMake against their respective library directories. This is
an easy task to do with `FIND_LIBRARY`.

Don't search iconv in /opt/local
Since OpenSSL isn't used any more on OS X, there is no dependency

system iconv can always be used now.
