A non-readable mapping of a file causes an access violation in
the pack tests. Always use PROT_READ to work around this.

Use size_t for page size, instead of long. Check result of sysconf.
Use size_t for page offset so no cast to size_t (second arg to p_mmap).
Use mod instead div/mult pair, so no cast to size_t is necessary.

Some OSs cannot keep their ideas about file content straight when mixing
standard IO with file mapping. As we use mmap for reading from the
packfile, let's make writing to the pack file use mmap.

This adds tests that try canceling an indexer operation from
within the progress callback.
After writing the tests, I wanted to run this under valgrind and
had a number of errors in that situation because mmap wasn't
working. I added a CMake option to force emulation of mmap and
consolidated the Amiga-specific code into that new place (so we
don't actually need separate Amiga code now, just have to turn on
-DNO_MMAP).
Additionally, I made the indexer code propagate error codes more
reliably than it used to.

There is a serious bug in the previous tree iterator implementation.
If case insensitivity resulted in member elements being equivalent
to one another, and those member elements were trees, then the
children of the colliding elements would be processed in sequence
instead of in a single flattened list. This meant that the tree
iterator was not truly acting like a case-insensitive list.
This completely reworks the tree iterator to manage lists with
case insensitive equivalence classes and advance through the items
in a unified manner in a single sorted frame.
It is possible that at a future date we might want to update this
to separate the case insensitive and case sensitive tree iterators
so that the case sensitive one could be a minimal amount of code
and the insensitive one would always know what it needed to do
without checking flags.
But there would be so much shared code between the two, that I'm
not sure it that's a win. For now, this gets what we need.
More tests are needed, though.

OpenBSD's realpath(3) doesn't require the last part of the path to
exist. Override p_realpath in this OS to bring it in line with the
library's assumptions.

The existing p_lstat implementation on win32 is not quite POSIX
compliant when setting errno to ENOTDIR. This adds an option to
make is be compliant so that code (such as checkout) that cares
to have separate behavior for ENOTDIR can use it portably.
This also contains a couple of other minor cleanups in the
posix_w32.c implementations to avoid unnecessary work.

This cleans up a number of items suggested during code review
with @vmg, including:
* renaming "outside repo" config API to `git_config_open_default`
* killing the `git_config_open_global` API
* removing the `git_` prefix from the static functions in fileops
* removing some unnecessary functionality from the "cp" command

This extends git_repository_init_ext further with support for
initializing the repository from an external template directory
and with support for the "create shared" type flags that make a
set GID repository directory.
This also adds tests for much of the new functionality to the
existing `repo/init.c` test suite.
Also, this adds a bunch of new utility functions including a
very general purpose `git_futils_mkdir` (with the ability to
make paths and to chmod the paths post-creation) and a file
tree copying function `git_futils_cp_r`. Also, this includes
some new path functions that were useful to keep the code
simple.

On RAM: the .idx and .pack files become links to a .lock and the original download respectively.
Assume some feature (such as record locking) supported by SFS but not JXFS or RAM: is required.

On Solaris, struct dirent is defined differently than Linux. The field
containing the path name is of size 0, rather than NAME_MAX. So, we need to
use a properly sized buffer on Solaris to avoid a stack overflow.
Also fix some DIR* leaks on cleanup.

Since Solaris does not support some of the same flags as glibc fnmatch(),
we just use the implementation we have for Windows.
Now that it's no longer a windows-specific thing, I moved it into compat/
instead of win32/

This converts the map validation function into a macro, tweaks
the GITERR_OS system error automatic appending, and adds a
tentative new error access API and some quick unit tests for
both the old and new error APIs.

This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to
the new style of error handling. Also got the unix and win32
versions of map.c. There are some minor changes to other
files but no others were completely converted.
This also contains an update to filebuf so that a zeroed out
filebuf will not think that the fd (== 0) is actually open
(and inadvertently call close() on fd 0 if cleaned up).
Lastly, this was built and tested on win32 and contains a
bunch of fixes for the win32 build which was pretty broken.

This is a major reorganization of the diff code. This changes
the diff functions to use the iterators for traversing the
content. This allowed a lot of code to be simplified. Also,
this moved the functions relating to outputting a diff into a
new file (diff_output.c).
This includes a number of other changes - adding utility
functions, extending iterators, etc. plus more tests for the
diff code. This also takes the example diff.c program much
further in terms of emulating git-diff command line options.

This fixes the missing readdir_r from win32 and fixes other
platforms to always use the reentrant readdir_r form for reading

1. The license header is technically not valid if it doesn't have a
copyright signature.
2. The COPYING file has been updated with the different licenses used in
the project.
3. The full GPLv2 header in each file annoys me.

Our good, lovely folks at Microsoft decided that there was no good
reason to make `vsnprintf` compilant with the C standard, so that
function in Windows returns -1 on overflow, instead of returning the
actual byte count needed to write the full string.
We now handle this situation more gracefully with the POSIX
compatibility layer, by returning the needed byte size using an
auxiliary method instead of blindly resizing the target buffer until it
fits.
This means we can now support `printf`s of any size by allocating a
temporary buffer. That's good.

The old `git_fileops_prettify_path` has been replaced with
`git_path_prettify`. This is a much simpler method that uses the OS's
`realpath` call to obtain the full path for directories and resolve
symlinks.
The `realpath` syscall is the original POSIX call in Unix system and
an emulated version under Windows using the Windows API.

Cleaned up the structure of the whole OS-abstraction layer.
fileops.c now contains a set of utility methods for file management used
by the library. These are abstractions on top of the original POSIX
calls.
There's a new file called `posix.c` that contains
emulations/reimplementations of all the POSIX calls the library uses.
These are prefixed with `p_`. There's a specific posix file for each
platform (win32 and unix).
All the path-related methods have been moved from `utils.c` to `path.c`
and have their own prefix.

It was not being used by any methods (only by malloc and calloc), and
since it needs to be TLS, it cannot be exported on DLLs on Windows.
Burn it with fire. The API always returns error codes!
