tree: fix integer overflow when reading unreasonably large filemodes
The `parse_mode` option uses an open-coded octal number parser. The
parser is quite naive in that it simply parses until hitting a character
that is not in the accepted range of '0' - '7', completely ignoring the
fact that we can at most accept a 16 bit unsigned integer as filemode.
If the filemode is bigger than UINT16_MAX, it will thus overflow and
provide an invalid filemode for the object entry.
Fix the issue by using `git__strntol32` instead and doing a bounds
check. As this function already handles overflows, it neatly solves the
problem.
Note that previously, `parse_mode` was also skipping the character
immediately after the filemode. In proper trees, this should be a simple
space, but in fact the parser accepted any character and simply skipped
over it. As a consequence of using `git__strntol32`, we now need to an
explicit check for a trailing whitespace after having parsed the
filemode. Because of the newly introduced error message, the test
object::tree::parse::mode_doesnt_cause_oob_read needs adjustment to its
error message check, which in fact is a good thing as it demonstrates
that we now fail looking for the whitespace immediately following the
filemode.
Add a test that shows that we will fail to parse such invalid filemodes
now.

tree: fix mode parsing reading out-of-bounds
When parsing a tree entry's mode, we will eagerly parse until we hit a
character that is not in the accepted set of octal digits '0' - '7'. If
the provided buffer is not a NUL terminated one, we may thus read
out-of-bounds.
Fix the issue by passing the buffer length to `parse_mode` and paying
attention to it. Note that this is not a vulnerability in our usual code
paths, as all object data read from the ODB is NUL terminated.

tree: add various tests exercising the tree parser
We currently don't have any tests that directly exercise the tree
parser. This is due to the fact that the parsers for raw object data has
only been recently introduce with commit ca4db5f4a (object: implement
function to parse raw data, 2017-10-13), and previous to that the setup
simply was too cumbersome as it always required going through the ODB.
Now that we have the infrastructure, add a suite of tests that directly
exercise the tree parser and various edge cases.

tree: accept null ids in existing trees when updating
When we add entries to a treebuilder we validate them. But we validate even
those that we're adding because they exist in the base tree. This disables
using the normal mechanisms on these trees, even to fix them.
Keep track of whether the entry we're appending comes from an existing tree and
bypass the name and id validation if it's from existing data.

treewide: remove use of C++ style comments
C++ style comment ("//") are not specified by the ISO C90 standard and
thus do not conform to it. While libgit2 aims to conform to C90, we did
not enforce it until now, which is why quite a lot of these
non-conforming comments have snuck into our codebase. Do a tree-wide
conversion of all C++ style comments to the supported C style comments
to allow us enforcing strict C90 compliance in a later commit.

tree: reject writing null-OID entries to a tree
In commit a96d3cc3f (cache-tree: reject entries with null sha1,
2017-04-21), the git.git project has changed its stance on null OIDs in
tree objects. Previously, null OIDs were accepted in tree entries to
help tools repair broken history. This resulted in some problems though
in that many code paths mistakenly passed null OIDs to be added to a
tree, which was not properly detected.
Align our own code base according to the upstream change and reject
writing tree entries early when the OID is all-zero.

Introduce a function to create a tree based on a different one
Instead of going through the usual steps of reading a tree recursively
into an index, modifying it and writing it back out as a tree, introduce
a function to perform simple updates more efficiently.
`git_tree_create_updated` avoids reading trees which are not modified
and supports upsert and delete operations. It is not as versatile as
modifying the index, but it makes some common operations much more
efficient.

treebuilder: use a map instead of vector to store the entries
Finding a filename in a vector means we need to resort it every time we
want to read from it, which includes every time we want to write to it
as well, as we want to find duplicate keys.
A hash-map fits what we want to do much more accurately, as we do not
care about sorting, but just the particular filename.
We still keep removed entries around, as the interface let you assume
they were going to be around until the treebuilder is cleared or freed,
but in this case that involves an append to a vector in the filter case,
which can now fail.
The only time we care about sorting is when we write out the tree, so
let's make that the only time we do any sorting.

Remove converting user error to GIT_EUSER
This changes the behavior of callbacks so that the callback error
code is not converted into GIT_EUSER and instead we propagate the
return value through to the caller. Instead of using the
giterr_capture and giterr_restore functions, we now rely on all
functions to pass back the return value from a callback.
To avoid having a return value with no error message, the user
can call the public giterr_set_str or some such function to set
an error message. There is a new helper 'giterr_set_callback'
that functions can invoke after making a callback which ensures
that some error message was set in case the callback did not set
one.
In places where the sign of the callback return value is
meaningful (e.g. positive to skip, negative to abort), only the
negative values are returned back to the caller, obviously, since
the other values allow for continuing the loop.
The hardest parts of this were in the checkout code where positive
return values were overloaded as meaningful values for checkout.
I fixed this by adding an output parameter to many of the internal
checkout functions and removing the overload. This added some
code, but it is probably a better implementation.
There is some funkiness in the network code where user provided
callbacks could be returning a positive or a negative value and
we want to rely on that to cancel the loop. There are still a
couple places where an user error might get turned into GIT_EUSER
there, I think, though none exercised by the tests.
