filters: introduce streaming filters
Add structures and preliminary functions to take a buffer, file or

of chained filters, finally writing into a user-provided function
accept the contents.

Make our overflow check look more like gcc/clang's
Make our overflow checking look more like gcc and clang's, so that
we can substitute it out with the compiler instrinsics on platforms
that support it. This means dropping the ability to pass `NULL` as
an out parameter.
As a result, the macros also get updated to reflect this as well.

attrcache: don't re-read attrs during checkout
During checkout, assume that the .gitattributes files aren't
modified during the checkout. Instead, create an "attribute session"
during checkout. Assume that attribute data read in the same
checkout "session" hasn't been modified since the checkout started.
(But allow subsequent checkouts to invalidate the cache.)
Further, cache nonexistent git_attr_file data even when .gitattributes
files are not found to prevent re-scanning for nonexistent files.

Be more careful with user-supplied buffers
This adds in missing calls to `git_buf_sanitize` and fixes a
number of places where `git_buf` APIs could inadvertently write
NUL terminator bytes into invalid buffers. This also changes the
behavior of `git_buf_sanitize` to NUL terminate a buffer if it can
and of `git_buf_shorten` to do nothing if it can.
Adds tests of filtering code with zeroed (i.e. unsanitized) buffer
which was previously triggering a segfault.

Add filter options and ALLOW_UNSAFE
Diff and status do not want core.safecrlf to actually raise an
error regardless of the setting, so this extends the filter API
with an additional options flags parameter and adds a flag so that
filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating
that unsafe filter application should be downgraded from a failure
to a warning.

Cleanups, renames, and leak fixes
This renames git_vector_free_all to the better git_vector_free_deep
and also contains a couple of memory leak fixes based on valgrind
checks. The fixes are specifically: failure to free global dir
path variables when not compiled with threading on and failure to
free filters from the filter registry that had not be initialized
fully.

Bug fixes and cleanups
This contains a few bug fixes and some header and API cleanups.
The main API change is that filters should now use GIT_PASSTHROUGH
to indicate that they wish to skip processing a file instead of
GIT_ENOTFOUND.
The bug fixes include a possible out-of-range buffer access in
the ident filter, a filter ordering problem I introduced into the
custom filter tests on Windows, and a filter buf NUL termination
issue that was coming up on Linux.

Some tests with ident and crlf filters
Fixed the filter order to match core Git, too.
This test demonstrates an interesting behavior of core Git (which
is totally reasonable and which libgit2 matches, although mostly
by coincidence). If you use the ident filter and commit a file
with a garbage ident in it, like '$Id: this is just garbage$' and
then immediately do a 'git checkout-index' with the new file, Git
will not consider the file out of date and will not overwrite the
file with an updated $Id$. Libgit2 has the same behavior. If you
remove the file and then do a checkout-index, it will be replaced
with a filtered version that has injected the OID correctly.

Merge git_buf and git_buffer
This makes the git_buf struct that was used internally into an
externally available structure and eliminates the git_buffer.
As part of that, some of the special cases that arose with the
externally used git_buffer were blended into the git_buf, such as
being careful about git_buf objects that may have a NULL ptr and
allowing for bufs with a valid ptr and size but zero asize as a
way of referring to externally owned data.

Add ident filter

Add functions to manipulate filter lists
Extend the git2/sys/filter API with functions to look up a filter
and add it manually to a filter list. This requires some trickery
because the regular attribute lookups and checks are bypassed when
this happens, but in the right hands, it will allow a user to have
granular control over applying filters.

Extend public filter api with filter lists
This moves the git_filter_list into the public API so that users
can create, apply, and dispose of filter lists. This allows more
granular application of filters to user data outside of libgit2
internals.
This also converts all the internal usage of filters to the public
APIs along with a few small tweaks to make it easier to use the
public git_buffer stuff alongside the internal git_buf.

Add attributes to filters and fix registry
The filter registry as implemented was too primitive to actually
work once multiple filters were coming into play. This expands
the implementation of the registry to handle multiple prioritized
filters correctly.
Additionally, this adds an "attributes" field to a filter that
makes it really really easy to implement filters that are based
on one or more attribute values. The lookup and even simple value
checking can all happen automatically without custom filter code.
Lastly, with the registry improvements, this fills out the filter
lifecycle callbacks, with initialize and shutdown callbacks that
will be called before the filter is first used and after it is
last invoked. This allows for system-wide initialization and
cleanup by the filter.

Consolidate text buffer functions
There are many scattered functions that look into the contents of
buffers to do various text manipulations (such as escaping or
unescaping data, calculating text stats, guessing if content is
binary, etc). This groups all those functions together into a
new file and converts the code to use that.
This has two enhancements to existing functionality. The old
text stats function is significantly rewritten and the BOM
detection code was extended (although largely we can't deal with
anything other than a UTF8 BOM).

Implement git_pool paged memory allocator
This adds a `git_pool` object that can do simple paged memory
allocation with free for the entire pool at once. Using this,
you can replace many small allocations with large blocks that
can then cheaply be doled out in small pieces. This is best
used when you plan to free the small blocks all at once - for
example, if they represent the parsed state from a file or data
stream that are either all kept or all discarded.
There are two real patterns of usage for `git_pools`: either
for "string" allocation, where the item size is a single byte
and you end up just packing the allocations in together, or for
"fixed size" allocation where you are allocating a large object
(e.g. a `git_oid`) and you generally just allocation single
objects that can be tightly packed. Of course, you can use it
for other things, but those two cases are the easiest.

filter: Apply filters before writing a file to the ODB
Initial implementation. The relevant code is in `blob.c`: the blob write
function has been split into smaller functions.
- Directly write a file to the ODB in streaming mode
- Directly write a symlink to the ODB in direct mode
- Apply a filter, and write a file to the ODB in direct mode
When trying to write a file, we first call `git_filter__load_for_file`,
which populates a filters array with the required filters based on the
filename.
If no filters are resolved to the filename, we can write to the ODB in
streaming mode straight from disk. Otherwise, we load the whole file in
memory and use double-buffering to apply the filter chain. We finish
by writing the file as a whole to the ODB.
