Clean up a provided absolute or relative directory path.

This prettification relies on basic operations such as coalescing multiple forward slashes into a single slash, removing '.' and './' current directory segments, and removing parent directory whenever '..' is encountered. If not empty, the returned path ends with a forward slash.

For instance, this will turn "d1/s1///s2/..//../s3" into "d1/s3/".

This only performs a string based analysis of the path. No checks are done to make sure the path actually makes sense from the file system perspective.

This will allow graceful migration to 64 bit file sizes and timestamps should
git's binary interface be extended to allow this.

Windows uses a 64 bit time_t by default and assigning to unsigned int causes a
64 -> 32 bit truncation warning. This change forces the truncation,
acknowledging the implications detailed in the file comments. Also, blobs are
limited to 32 bit file sizes for the same reason (on all platforms).

Off_t is not cool. It can be 32 or 64 bits depending on the platform,
but on the Index format, it's always 32 bits.

- remove() would read one-past array bounds.
- resize() would fail if the initial size was 1, because it multiplied by 1.75
  and truncated the resulting value. The buffer would always remain at size 1,
  but elements would repeatedly be appended (via insert()) causing a crash.

Major changes and rationale:
- /WX: absolutely vital when compiling in C-mode as the compiler is
  incredibly lenient on what is allowed to compile. It allows functions to be
  called without prototypes declared, treating them as functions returning int
  taking an unspecified (read: unrestricted) list of arguments, without any
  type checking! It will simply issue a warning, which is easily overlooked.

  A real example: it will allow you to call ceil(1.75) without first including
  <math.h> causing UB, returning bogus results like 1023 on the machine I
  tested on.

- Release build separate from debug.
  Presently release builds don't exist.  Consequently they are completely
  untested. Many bugs may only manifest themselves in release mode. The current
  configuration sets debug-only flags like /RTC1 which are incompatible with
  optimization (/O2).

  In addition, the Windows build of libgit2 has no optimized version. This
  change resolves this.

- Added checksum generation in image headers. This is so debuggers don't
  complain about checksum mismatches and provides a small amount of consistency
  to binaries.

Use this for hashing strings on hash tables instead
of a full SHA1 hash. It's very fast and well distributed.

Fix the test building issues once for all; each test is linked
with the raw objects of the library, not with any compiled version. That
way we make sure the tests always run, and are always linked with the
latest and most up-to-date version of the code.
