Add a file reading routine along with an io buffer type
In particular, the gitfo_read_file() routine can be used to slurp
the complete file contents into an gitfo_buf structure. The buffer
content will be allocated by malloc() and may be released by the
gitfo_free_buf() routine. The io buffer type can be initialised
on the stack with the GITFO_BUF_INIT macro.

Add a GIT_PATH_MAX constant
The PATH_MAX symbol is often, but not always, defined
in the <limits.h> header. In particular, on cygwin you
need to include this header to avoid a compilation error.
However, some systems define PATH_MAX to be something as
small as 256, which POSIX is happy to allow, while others
allow much larger values. In general it can vary from
one filesystem to another.
In order to avoid the vagaries of different systems, define
our own symbol.

Since at least MS have something like GetFirstDirEnt() and

Add an io caching layer to the gitfo api
The idea is taken from Junio's work in read-cache.c, where
it's used for writing out the index without tap-dancing on
the poor harddrive. Since it's almost certainly useful for
cached writing of packfiles too, we turn it into a generic
API, making it perfectly simple to reuse it later.
gitfo_write_cached() has the same contract as gitfo_write(), it
returns GIT_SUCCESS if all bytes are successfully written (or were
at least buffered for later writing), and <0 if an error occurs
during buffer writing.

Remove config.h and make fileops an internal API
Since it doesn't make sense to make the disk access stuff
portable *AND* public (that's a job for each application
imo), we can take a shortcut and just support unixy stuff
for now and get away with coding most of it as macros.
Since we go with an internal API for starters and only
provide higher-level API's to the libgit users, we'll be
ok with this approach.

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.

Move public headers to src/git
It's arguably smoother to keep them close to the source,
as that's where one's working when modifying them. More
importantly, though, is the ability to use private headers
in the src/ dir that simply include "git/$samename.h" to
get to the public API at the same time.

s/git_revp/git_revpool/
git_revp is something I personally can't stop pronouncing
"rev pointer". I'm sure others would suffer the same
problem.
Also, rename the git_revp_ sub-api "gitrp_". This is the
first of many such renames, primarily done to prevent
extreme inflation in the "git_" namespace, which we'd like
to reserve for a higher-level API.
While we're at it, we remove the noise-char "c" from a lot
of functions. Since revision walking is all about commits,
the common case should be that we're dealing with commits.
Exceptions can get a more mnemonic description as needed.

Add git_oid_cpy, git_oid_cmp as inline functions
These are easily built off the standard C library functions memcpy

the C compiler replacing the entire thing with tight machine code,
because many compilers will actually inline a memcmp or memcpy when
the 3rd argument (the size) is a constant value.

Scratch the git_revp_attr configuration of a git_revp
This isn't the best idea I've head. Pierre Habouzit was suggesting
a technique of assigning a unique integer to each commit and then
allocating storage out of auxiliary pools, using the commit's unique
integer to index into any auxiliary pool in constant time. This way
both applications and the library can efficiently attach arbitrary
data onto a commit, such as rewritten parents, or flags, and have
them disconnected from the main object hash table.
