Changed revpool's object table to support arbitrary objects
git_revpool_object now has a type identifier for each object
type in a revpool (commits, trees, blobs, etc).
Trees can now be stored in the revision pool.
git_revpool_tableit now supports filtering objects by their
type when iterating through the object table.

Fix a "dereference of type-punned pointer" compiler warning
gcc (4.4.0) issues the following warning:
src/revobject.c:33: warning: dereferencing type-punned pointer \
will break strict-aliasing rules
We suppress the warning by copying the first 4 bytes from the oid
structure into an 'unsigned int' using memcpy(). This will also
fix any potential alignment issues on certain platforms.

Fix sparse warnings: "symbol not declared. Should it be static?"
In particular, sparse issues the following warnings:
src/revobject.c:29:14: warning: symbol 'max_load_factor' was \
not declared. Should it be static?
src/revobject.c:31:14: warning: symbol 'git_revpool_table__hash' was \
not declared. Should it be static?
In order to suppress these warnings, we simply declare them as
static, since they are not (currently) referenced outside of this
file.
In the case of max_load_factor, this is probably correct. However,
this may not be appropriate for git_revpool_table__hash(), given
how it is named. So, this should either be re-named to reflect it's
non-external status, or a declaration needs to be added to the
revobject.h header file.

msvc: Fix some compiler warnings
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.

Fix a memory corruption runtime error
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.

Add object cache to the revision pool.
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.

Add 'git_revpool_object' and 'git_revpool_table' structures.
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.
