commit_list: store in/out-degrees as uint16_t
The commit list's in- and out-degrees are currently stored as `unsigned
short`. When assigning it the value of `git_array_size`, which returns
an `size_t`, this generates a warning on some Win32 platforms due to
loosing precision.
We could just cast the returned value of `git_array_size`, which would
work fine for 99.99% of all cases as commits typically have less than
2^16 parents. For crafted commits though we might end up with a wrong
value, and thus we should definitely check whether the array size
actually fits into the field.
To ease the check, let's convert the fields to store the degrees as
`uint16_t`. We shouldn't rely on such unspecific types anyway, as it may
lead to different behaviour across platforms. Furthermore, this commit
introduces a new `git__is_uint16` function to check whether it actually
fits -- if not, we return an error.

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

revwalk: get closer to git
We had some home-grown logic to figure out which objects to show during
the revision walk, but it was rather inefficient, looking over the same
list multiple times to figure out when we had run out of interesting
commits. We now use the lists in a smarter way.
We also introduce the slop mechanism to determine when to stpo
looking. When we run out of interesting objects, we continue preparing
the walk for another 5 rounds in order to make it less likely that we
miss objects in situations with complex graphs.

revwalk: make commit list use 64 bits for time
We moved the "main" parsing to use 64 bits for the timestamp, but the
quick parsing for the revwalk did not. This means that for large
timestamps we fail to parse the time and thus the walk.
Move this parser to use 64 bits as well.

Replace pqueue with code from hashsig heap
I accidentally wrote a separate priority queue implementation when
I was working on file rename detection as part of the file hash
signature calculation code. To simplify licensing terms, I just
adapted that to a general purpose priority queue and replace the
old priority queue implementation that was borrowed from elsewhere.
This also removes parts of the COPYING document that no longer
apply to libgit2.

Move merge functions to merge.c
In so doing, promote commit_list to git_commit_list,
with its own internal API header.
