Colin Walters 27c3e7884e core: Make write_object() a bit more efficient 
Do as many operations as we can using the original file descriptor
while we have it open, rather than writing, closing, then reopening.

This necessitated very explicitly special casing symbolic links,
mainly due to the lack of lsetxattrat().

Colin Walters 9846fb27fd core: Use linkat() for hardlink checkouts too 
Clean up how we deal with the uncompressed object cache; we now use
openat()/linkat() and such just like we do for the main objects/.

Use linkat() between the objects and the destination, if possible.

Jasper St. Pierre 1f8db2a873 repo: Drop the branch parameter from ostree_repo_commit 
It's unused. Make users explicitly write a ref if they want this;
high-level convenience API will be introduced later.

Jasper St. Pierre 8ac0f99ed6 repo-file: s/content_checksum/contents_checksum/ 
This is what we call it everywhere else, so just be consistent.
It also lines up with metadata_checksum better.

Colin Walters b97249d4f9 core: Use at-relative lookup for locating objects too 
Add new internal API to both fstatat() and write a pathname for the
given object.  Use it in commit, and also wrapped in the old
GFile-based API.

This is more efficient.

Colin Walters a7c0992d94 core: Add malloc-free API for objects, use *at functions for storing 
This is more efficient; we avoid malloc of a number of pathname +
GFile objects, plus the kernel doesn't have to traverse the repo path
again.

Jasper St. Pierre 3dcff0b2c4 Fix build 
Before I pushed the "move code to a different file" commit, I rebased,
but forgot to test the build. Sorry.

Jasper St. Pierre 91d3b90c9f Move ref writing to be transaction-based 
Rather than having separate write_ref calls, make clients start a
transaction, add some refs, and then commit it. While this doesn't
make it 100% atomic, it makes it easier for us to use an atomic
model, and it means we don't do as much I/O updating the summary
file and such.

Jasper St. Pierre bd2948e964 repo: Move the scanning hardlinks optimization out of prepare_transaction 
This is just a terrible API to have. Make the scanning a separate method,
and document it as an optimization.

Jasper St. Pierre f84504a8c4 repo: Make abort_transaction silently succeed if we're not in a transaction 
This helps callers out a lot, and means we can always call abort_transaction
at the end of a function.

Jasper St. Pierre ef61724269 repo: Move the transaction stats to a separate struct 
This is much easier for callers to handle, and simplifies
the API a lot.

Jasper St. Pierre 5082e1d8e9 repo: Rename "stage" to "write" in the API 
An earlier version of this API acted like git in that some objects
would be staged in a temporary directory which would be then committed
in one go by moving files around. The API doesn't match most users
expectations though, as while the stage is nice as a high-level API
it isn't really suited for low-level APIs.

While the stage was removed, the APIs were never renamed. Rename
them now so that they match expectations.

Jasper St. Pierre c817217ad8 repo: Move commit code to another file 
ostree-repo.c is a bit too big, and most of the commit code is
fairly standalone.
