Add proper threading support to libgit2
We now depend on libpthread on all Unix platforms (should be installed
by default) and use a simple wrapper for Windows threads under Win32.

Improve the performance when writing Index files
In response to issue #60 (git_index_write really slow), the write_index
function has been rewritten to improve its performance -- it should now
be in par with the performance of git.git.
On top of that, if Posix Threads are available when compiling libgit2, a
new threaded writing system will be used (3 separate threads take care
of solving byte-endianness, hashing the contents of the index and
writing to disk, respectively). For very long Index files, this method
is up to 3x times faster than git.git.

Revert "Properly export all external symbols in Win32"
It is not a good idea to export these internal symbols now that they are
not required to run the unit tests.

Properly export all external symbols in Win32
Some external functions were not being exported because they were using
the 'extern' keyword instead of the generic GIT_EXTERN() macro.

thread-utils.h: Avoid using a non-standard C construct
In particular, in standard C, a struct or union must have at
least one member declared (ie. structs and unions cannot be
empty). Some compilers allow empty structs as an extension
and won't even issue a warning unless asked for it (eg, gcc
requires -pedantic). Some compilers allow empty structs as
an extension and will only treat it as an error if asked for
strict checking (eg Digital-Mars with -A). Some compilers
simply treat it as an error (eg MS Visual C/C++).

Change the use of asm/atomic.h to require -DGIT_HAS_ASM_ATOMIC
These headers aren't always available; they typically come from the
Linux kernel, but aren't supposed to be exported into the userspace
/usr/include. Modern kernels won't install these and some distros
rm -rf the directory post kernel header install.

Add a mutex and atomic counter abstraction and implementations
These abstractions can be used to implement an efficient resource
reference counter and simple mutual exclusion. On pthreads we use
pthread_mutex_t, except when we are also on glibc and can directly
use its asm/atomic.h definitions.

Add compiler/platform agnostic thread-local storage
It doesn't cover all cases, but we can work on those as
we go along. For now, gcc, MSVC++, Intel C/C++, IBM XL C/C++,
Sun Studio C/C++ and Borland C++ Builder are the supported
compilers (although we boldly assume that they all are of
a recent enough version to support thread-local storage).
This is intended to be used in upcoming patches that implement
graceful (but TLS-dependant) error-handling in the library.
As an added bonus, we also bring the online_cpus() function
from git.git to detect the number of usable cpu's.
