In particular, the compiler issues the following warnings:
src/revobject.c(29) : warning C4305: 'initializing' : truncation \
from 'double' to 'const float'
src/revobject.c(56) : warning C4244: '=' : conversion from \
'const float' to 'unsigned int', possible loss of data
src/revobject.c(149) : warning C4244: '=' : conversion from \
'const float' to 'unsigned int', possible loss of data
In order to suppress the warnings we change the type of max_load_factor
to double, rather than change the initialiser to 0.65f, and cast the
result type of the expressions to 'unsigned int' as expected by the
assignment operators. Note that double should be able to represent all
unsigned int values without loss.

On the msvc build, the tests t0401-parse and t0501-walk both
crash with a runtime error (ACCESS_VIOLATION). This is caused
by writing to un-allocated memory due to an under-allocation
of a git_revpool_table data structure.

Fixed issue when generating pending commits list during iteration.
The 'git_commit_lookup' function will now check the pool's cache
for commits which have been previously loaded/parsed; there can only
be a single 'git_commit' structure for each commit on the same pool.

All the objects which will will be eventually transversable from
a revision pool (commits, trees, etc) now inherit from the
'git_revpool_object' structure which identifies them with their
own OID.
Furthermore, the 'git_revpool_table' and related functions have
been added, which allow for constant time lookup (hash table)
of the loaded revpool objects based on their OID.

Basic support for iterating the revpool.
The following functions of the revwalk API have been partially
implemented:
void gitrp_reset(git_revpool *pool);
void gitrp_push(git_revpool *pool, git_commit *commit);
void gitrp_prepare_walk(git_revpool *pool);
git_commit *gitrp_next(git_revpool *pool);
Parsed commits' parents are now also parsed and stored in a
"git_commit_list" structure (linked list).

A few initial tests for commit parsing:
"parse_buffer_test" tests git_commit__parse_buffer() with
several malformed commit messages and a few corner cases
which should pass.
"parse_oid_test" tests git_commit__parse_oid() with several
malformed commit lines containing broken SHA1 OIDs.

The external API function "git_commit_parse" has been renamed
to "git_commit_lookup" and has been partially implemented with
support for loading commits straight from the ODB. It still lacks
the functionality to lookup cached commits in the revpool and to
resolve tags to commits.
The following internal functions have been partially implemented:
int git_commit__parse_buffer(...);
int git_commit__parse_time(...);
int git_commit__parse_oid(...);
Commits are now fully parsed but the generated parent and tree
references are not handled yet.

Commit 5dddf7c (Add block-sha1 in favour of the mozilla routines
2010-04-14) introduced the "bswap.h" header file which, for x86
or x86-64 machines, provides a "sane" implementation of ntohl()
and htonl().
The wsock32 library, on the msvc and MinGW build, is only included
in the link to supply the ntohl()/htonl() routines. Since we now
have a built-in implementation, we can remove the wsock32 library
from the link.

Commit 5dddf7c (Add block-sha1 in favour of the mozilla routines
2010-04-14) introduced the "bswap.h" header file which contains
an inline function (default_swab32()). The msvc compiler does
not support the inline keyword which causes the build to fail
with a syntax error.
However, msvc does support inline functions using the __inline
keyword language extension. We already have the GIT_INLINE()
macro that allows us to hide this syntatic difference. In order
to fix the build, we simply use GIT_INLINE() in the definition
of the default_swab32() function.

Fix some coding style issues
Since block-sha1 from git.git has such excellent performance, we
can also get rid of the openssl dependency. It's rather simple
to add it back later as an optional extra, but we really needn't
bother to pull in the entire ssl library and have to deal with
linking issues now that we have the portable and, performance-wise,
truly excellent block-sha1 code to fall back on.
Since this requires a slight revamp of the build rules anyway, we
take the opportunity to fix including EXTRA_OBJS in the final build
as well.
The block-sha1 code was originally implemented for git.git by
Linus Torvalds <torvalds@linux-foundation.org> and was later
polished by Nicolas Pitre <nico@cam.org>.

Given an index entry number, the idx_get() function returns an
(version agnostic) index_entry structure containing all of the
information required to unpack the corresponding object from
the '.pack' file.
Since the v1 and v2 file formats differ in the layout of the
object records, we provide two implementations of the get
function and initialise the function pointer appropriately.
