Add support for git index files
The new 'git_index' structure is an in-memory representation
of a git index on disk; the 'git_index_entry' structures represent
each one of the file entries on the index.
The following calls for index instantiation have been added:
git_index_alloc(): instantiate a new index structure
git_index_free(): free an existing index
git_index_clear(): clear all the entires in an existing file
The following calls for index reading and writing have been added:
git_index_read(): update the contents of the index structure from
its file on disk.
Internally implemented through:
git_index__parse()
Index files are stored on disk in network byte order; all integer fields
inside them are properly converted to the machine's byte order when
loading them in memory. The parsing engine also distinguishes
between normal index entries and extended entries with 2 extra bytes
of flags.
The 'TREE' extension for index entries is also loaded into memory:
Tree caches stored in Index files are loaded into the
'git_index_tree' structure pointed by the 'tree' pointer inside
'git_index'.
'index->tree' points to the root node of the tree cache; the full tree
can be traversed through each of the node's 'tree->children'.
Index files can be written back to disk through:
git_index_write(): atomic writing of existing index objects
backed by internal method git_index__write()
The following calls for entry manipulation have been added:
git_index_add(): insert an empty entry to the index
git_index_find(): search an entry by its path name
git_index__append(): appends a new index entry to the end of the
list, resizing the entries array if required
New index entries are always inserted at the end of the array; since the
index entries must be sorted for it to be internally consistent, the
index object is only sorted once, and if required, before accessing the
whole entriea array (e.g. before writing to disk, before traversing,
etc).
git_index__remove_pos(): remove an index entry in a specific position
git_index__sort(): sort the entries in the array by path name
The entries array is sorted stably and in place using an
insertion sort, which ought to be the most efficient approach
since the entries array is always mostly-sorted.

Redesigned the walking/object lookup interface
The old 'git_revpool' object has been removed and
split into two distinct objects with separate
functionality, in order to have separate methods for
object management and object walking.
* A new object 'git_repository' does the high-level
management of a repository's objects (commits, trees,
tags, etc) on top of a 'git_odb'.
Eventually, it will also manage other repository
attributes (e.g. tag resolution, references, etc).
See: src/git/repository.h
* A new external method
'git_repository_lookup(repo, oid, type)'
has been added to the 'git_repository' API.
All object lookups (git_XXX_lookup()) are now
wrappers to this method, and duplicated code
has been removed. The method does automatic type
checking and returns a generic 'git_revpool_object'
that can be cast to any specific object.
See: src/git/repository.h
* The external methods for object parsing of repository
objects (git_XXX_parse()) have been removed.
Loading objects from the repository is now managed
through the 'lookup' functions. These objects are
loaded with minimal information, and the relevant
parsing is done automatically when the user requests
any of the parsed attributes through accessor methods.
An attribute has been added to 'git_repository' in
order to force the parsing of all the repository objects
immediately after lookup.
See: src/git/commit.h
See: src/git/tag.h
See: src/git/tree.h
* The previous walking functionality of the revpool
is now found in 'git_revwalk', which does the actual
revision walking on a repository; the attributes
when walking through commits in a database have been
decoupled from the actual commit objects.
This increases performance when accessing commits
during the walk and allows to have several
'git_revwalk' instances working at the same time on
top of the same repository, without having to load
commits in memory several times.
See: src/git/revwalk.h
* The old 'git_revpool_table' has been renamed to
'git_hashtable' and now works as a generic hashtable
with support for any kind of object and custom hash
functions.
See: src/hashtable.h
* All the relevant unit tests have been updated, renamed
and grouped accordingly.

Add external API to access detailed commit attributes
The following new external methods have been added:
GIT_EXTERN(const char *) git_commit_message_short(git_commit *commit);
GIT_EXTERN(const char *) git_commit_message(git_commit *commit);
GIT_EXTERN(time_t) git_commit_time(git_commit *commit);
GIT_EXTERN(const git_commit_person *) git_commit_committer(git_commit *commit);
GIT_EXTERN(const git_commit_person *) git_commit_author(git_commit *commit);
GIT_EXTERN(const git_tree *) git_commit_tree(git_commit *commit);
A new structure, git_commit_person has been added to represent a
commit's author or committer.
The parsing of a commit has been split in two phases.
When adding a commit to the revision pool:
- the commit's ODB object is opened
- its raw contents are parsed for commit TIME, PARENTS and TREE
(the minimal amount of data required to traverse the pool)
- the commit's ODB object is closed
When querying for extended information on a commit:
- the commit's ODB object is reopened
- its raw contents are parsed for the requested information
- the commit's ODB object remains open to handle additional queries
New unit tests have been added for the new functionality:
In t0401-parse: parse_person_test
In t0402-details: query_details_test

Fix inconsistent definition of off_t on Linux
In order to avoid inconsistent definitions of type off_t, all
compilation units should include the "common.h" header file
before certain system headers (those which directly or indirectly
lead to the definition of off_t). The "common.h" header contains
the definition of _FILE_OFFSET_BITS to select 64-bit file offsets.
The symptom of this inconsistency, while compiling with -Wextra, is
the following warning:

from src/commit.c:28:
src/util.h: In function git__is_sizet:

In order to suppress these warnings, we simply declare them as

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

int git_commit__parse_oid(...);

win32: Remove wsock32 from the list of libraries to link
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.

MSVC: Fix a syntax error caused by an inline function definition
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.

Add block-sha1 in favour of the mozilla routines
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>.

Add a pack index 'virtual function' to fetch an index entry
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.

Add a pack index 'virtual function' to search by file offset
In addition to searching the index by oid, we need to search by
'.pack' file offset, particularly when processing OBJ_OFS_DELTA
objects. Since the v1 and v2 file formats differ in the layout
of the object records, we provide two implementations of the
search function and initialise the (virtual) function pointer
appropriately.
Note that, as part of the creation of the 'offset index', we also
add a check that the offset data in the index is within the bounds
of the '.pack' file. Having sorted the file offsets, while creating
the index, we only need to check the smallest and largest values.
The offset index consists of the im_off_idx array, which contains
the index entry numbers sorted into file offset order, and the
im_off_next mapping array. The im_off_next array maps an index
entry number to the 'next' index entry in file offset order.
