f0bde7fac0 Revised platform types to use 'best supported' size.
This will allow graceful migration to 64 bit file sizes and timestamps should
git's binary interface be extended to allow this.

e035685f27 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.

2a18a792e3 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.

6fd195d76c Change git_repository initialization to use a path
The constructor to git_repository is now called

	'git_repository_open(path)'

and takes a path to a git repository instead of an existing ODB object.
Unit tests have been updated accordingly and the two test repositories
have been merged into one.

c79dded300 win32: Add an fsync() implementation for windows
For information on FlushFileBuffers(), see the msdn document
at msdn.microsoft.com/en-us/library/aa364439(VS.85).aspx

Note that Windows 2000 is shown as the minimum windows version
to support FlushFileBuffers(), so if we wish to support Win9X
and NT4, we will need to add code to dynamically check if
kernel32.dll contains the function.

The only error return mentioned in the msdn document is
ERROR_INVALID_HANDLE, which is returned if the file/device
(eg console) is not buffered. The fsync(2) manpage says that
EINVAL is returned in errno, if "fd is bound to a special
file which does not support synchronization".

498bc09068 t0020-dirent.c: allow test to be run standalone
This test assumed that it was invoked in an empty directory,
which is true when run from the Makefile, and so would fail
if run standalone. In order to allow the test to work when
run from any directory, create a sub directory "dir-walk"
and chdir() into this directory while running the tests.

Also, add some additional tests.

7a6cf81537 win32: Open or create files in binary mode
On windows, unless we use the O_BINARY flag in the open()
call, the file I/O routines will perform line ending
conversion (\r\n => \n on input, \n => \r\n on output).
In addition to the performance penalty, most files in the
object database are binary and will, therefore, become
corrupted by this conversion.

20e7f426c3 Add a simple mmap wrapper for cross-platform mmap usage
Win32 has a variant of mmap that is harder to use than POSIX, but
to run natively and efficiently on Win32 we need some form of it.

gitfo_map_ro() provides a basic mmap function for use in locations
where we need read-only random data access to large ranges of a file,
such as a pack-*.idx.

5690f02e87 Rewrite git_foreach_dirent into gitfo_dirent
Our fileops API is currently private.  We aren't planning on supplying
a cross-platform file API to applications that link to us.  If we did,
we'd probably whole-sale publish fileops, not just the dirent code.

By moving it to be private we can also change the call signature to
permit the buffer to be passed down through the call chain.  This is
very helpful when we are doing a recursive scan as we can reuse just
one buffer in all stack frames, reducing the impact the recursion has
on the stack frames in the data cache.

75d5843055 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.

ea790f337b Add a dirent walker to the fileops API
Since at least MS have something like GetFirstDirEnt() and
GetNextDirEnt() (presumably with superior performance), we
can let MS hackers add support for a dirent walker using
that API instead, while we stick with the posix-style
readdir() calls.

4188d28f1c 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.

ec250c6e18 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.
