Share packs across repository instances
Opening the same repository multiple times will currently open the same
file multiple times, as well as map the same region of the file multiple
times. This is not necessary, as the packfile data is immutable.
Instead of opening and closing packfiles directly, introduce an
indirection and allocate packfiles globally. This does mean locking on
each packfile open, but we already use this lock for the global mwindow
list so it doesn't introduce a new contention point.

indexer: mmap fixes for Windows
Windows has its own ftruncate() called _chsize_s().
p_mkstemp() is changed to use p_open() so we can make sure we open for
writing; the addition of exclusive create is a good thing to do
regardless, as we want a temporary path for ourselves.
Lastly, MSVC doesn't quite know how to add two numbers if one of them is a
void pointer, so let's alias it to unsigned char.C

indexer: avoid memory moves
Our vector does a move of the rest of the array when we remove an
item. Doing this repeatedly can be expensive, and we do this a lot in
the indexer. Instead, set the value to NULL and skip those entries.
perf reported around 30% of `index-pack` time was going into
memmove. With this change, that goes away and we spent most of the time
hashing and inflating data.

This renames git_vector_free_all to the better git_vector_free_deep

checks. The fixes are specifically: failure to free global dir
path variables when not compiled with threading on and failure to
free filters from the filter registry that had not be initialized
fully.

Test cancel from indexer progress callback
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.

Remove converting user error to GIT_EUSER
This changes the behavior of callbacks so that the callback error
code is not converted into GIT_EUSER and instead we propagate the
return value through to the caller. Instead of using the
giterr_capture and giterr_restore functions, we now rely on all
functions to pass back the return value from a callback.
To avoid having a return value with no error message, the user
can call the public giterr_set_str or some such function to set
an error message. There is a new helper 'giterr_set_callback'
that functions can invoke after making a callback which ensures
that some error message was set in case the callback did not set
one.
In places where the sign of the callback return value is
meaningful (e.g. positive to skip, negative to abort), only the
negative values are returned back to the caller, obviously, since
the other values allow for continuing the loop.
The hardest parts of this were in the checkout code where positive
return values were overloaded as meaningful values for checkout.
I fixed this by adding an output parameter to many of the internal
checkout functions and removing the overload. This added some
code, but it is probably a better implementation.
There is some funkiness in the network code where user provided
callbacks could be returning a positive or a negative value and
we want to rely on that to cancel the loop. There are still a
couple places where an user error might get turned into GIT_EUSER
there, I think, though none exercised by the tests.

Add git_vector_free_all
There are a lot of places that we call git__free on each item in

Further EUSER and error propagation fixes
This continues auditing all the places where GIT_EUSER is being
returned and making sure to clear any existing error using the
new giterr_user_cancel helper. As a result, places that relied
on intercepting GIT_EUSER but having the old error preserved also
needed to be cleaned up to correctly stash and then retrieve the
actual error.
Additionally, as I encountered places where error codes were not
being propagated correctly, I tried to fix them up. A number of
those fixes are included in the this commit as well.

indexer: remove the stream infix
It was there to keep it apart from the one which read in from a file on
disk. This other indexer does not exist anymore, so there is no need for
anything other than git_indexer to refer to it.
While here, rename _add() function to _append() and _finalize() to
_commit(). The former change is cosmetic, while the latter avoids
talking about "finalizing", which OO languages use to mean something
completely different.

indexer: include the delta stats
The user is unable to derive the number of deltas in the pack, as that
would require them to capture the stats exactly in the moment between
download and final processing, which is abstracted away in the fetch.
Capture these numbers for the user and expose them in the progress
struct. The clone and fetch examples now also present this information
to the user.

indexer: do multiple passes over the delta list
Though unusual, a packfile may contain a delta whose base is a delta
that comes later. In order index such a packfile, we must not give up
on the first failure to resolve a delta, but keep it around.
If there is a pass which makes no progress, this indicates that the
packfile is broken, so fail accordingly.

Support cancellation in push operation
This commit adds cancellation for the push operation. This work consists of:
1) Support cancellation during push operation
- During object counting phase
- During network transfer phase
- Propagate GIT_EUSER error code out to caller
2) Improve cancellation support during fetch
- Handle cancellation request during network transfer phase
- Clear error string when cancelled during indexing
3) Fix error handling in git_smart__download_pack
Cancellation during push is still only handled in the pack building and
network transfer stages of push (and not during packbuilding).

Make indexer use shared packfile open code
The indexer was creating a packfile object separately from the
code in pack.c which was a problem since I put a call to
git_mutex_init into just pack.c. This commit updates the pack
function for creating a new pack object (i.e. git_packfile_check())
so that it can be used in both places and then makes indexer.c
use the shared initialization routine.
There are also a few minor formatting and warning message fixes.

indexer: use a hashtable for keeping track of offsets
These offsets are needed for REF_DELTA objects, which encode which
object they use as a base, but not where it lies in the packfile, so
we need a list.
These objects are mostly from older packfiles, before OFS_DELTA was
widely spread. The time spent in indexing these packfiles is greatly
reduced, though remains above what git is able to do.

indexer: make use of streaming also for deltas
Up to now, deltas needed to be enterily in the packfile, and we tried
to decompress then in their entirety over and over again.
Adjust the logic so we read them as they come, just as we do for full
objects. This also allows us to simplify the logic and have less
nested code. The delta resolving phase still needs to decompress the
whole object into memory, as there is not yet any streaming
delta-apply support, but it helps in speeding up the downloading
process and reduces the amount of memory allocations we need to do.

indexer: use the packfile streaming API
The new API allows us to read the object bit by bit from the packfile,
instead of needing it all at once in the packfile. This also allows us
to hash the object as it comes in from the network instead of having
to try to read it all and failing repeatedly for larger objects.
This is only the first step, but it already shows huge improvements
when dealing with objects over a few megabytes in size. It reduces the
memory needs in some cases, but delta objects still need to be
completely in memory and the old inefficent method is still used for
that.

Currently, the first call of git_indexer_stream_add adds the data to the
underlying pack file and opens it for later use, but doesn't start
parsing the already available data.
This means, git_indexer_stream_finalize only works if
git_indexer_stream_add was called at least twice. Kill this limitation
by parsing available data immediately.

Actually do the mmap... unsurprisingly, this makes the indexer work on SFS
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.

transports: buffer the git requests before sending them
Trying to send every single line immediately won't give us any speed
improvement and duplicates the code we need for other transports. Make
the git transport use the same buffer functions as HTTP.

indexer: start writing the stream indexer
This will allow us to index a packfile as soon as we receive it from
the network as well as storing it with its final name so we don't need
to pass temporary file names around.
