88a130da09 lib: Extract bwrap-executing internal API
The treecompose code will learn how to use bwrap instead of
libcontainer in libglnx, since the latter is a buggy copy of a subset
of the former.

39913a2c25 Update for libhif -> libdnf
Still not many PRs outstanding, so it's a good time to take this plunge.
Mostly automated via `sed`.

125c482b1d Switch to using libhif as a git submodule
So I was trying to hack on my host's copy of rpm-ostree inside a pet
docker container, but ran into a conflict with libhif since dnf uses
it.  I think we basically need to *always* build the bundled path,
rather than what I'm doing with CAHC and FADC where it's built as a
regular RPM.

It's not really sustainable right now for us to have both bundled and
not-bundled build paths - and we need to support co-installation with
dnf.

Another major issue is that we want to version lock with libhif -
right now our CI and both CAHC/FADC track libhif master, but that
means everything breaks if libhif breaks and we don't immediately
port.

git submodules solve all of these problems - the same as we're doing
with libglnx.

libglnx is *designed* for use as a git submodule, where as libhif
needs to support being both bundled and not-bundled.  So we end up
with some hacks on our side, but I think it's all not too bad.  I've
marked build rules with `# bundled libhif` so we know where to find
them later when libhif is stable.

f35f5cf468 core: Initial implementation of %posttrans using bwrap+rofiles-fuse
In order to make many things work, we need to run scripts.  Short version:
For now, we:

 - Run `%posttrans`
 - Treat most `%post` as the same as `%posttrans`
 - Ignore `%preun` and such since we never uninstall

Most importantly though, we start to build up an "override" list
for script handling.  Currently it's just a blacklist of scripts
we don't need.

Significant work here would be needed to run Lua scripts, so far I've
been able to just skip them.

20e69a9692 status: Import systemd bits to use UTF-8 circle
It's slightly prettier, but this is just laying some
groundwork/precedent for importing more systemd code and using it for
our formatting.

b3a7b4e218 Rename rpmostree-hif.[ch] -> core
This is really going to be the heart of rpm-ostree, so let's give it a
better name.

b716959252 Major revamp/extension of libhif/unpacker code
This is in preparation for `rpm-ostree container`, which handles
unpacking RPMs as non-root.

At the moment, I'm copying code in from both ostree's libarchive bits
(fixable...may need to export some utility functions) and some
functions from libhif (harder, see:
http://lists.rpm.org/pipermail/rpm-ecosystem/2016-January/000297.html )

There's lots more cleanup to do here, but I don't want to block on the
resolution of the libhif changes.

ec4387afba internals: New unpack verb
This is part of taking over from librpm.  The most important high
level goal is fully unprivilged operation.

Right now we're basically starting to do what
http://libguestfs.org/supermin.1.html does, except in C, and
faster.

There's no reason that `compose tree` should require privileges.
However right now, things like `%post` scripts will want to run in the
target root - so we'd have to require `linux-user-chroot`.

Regardless of unprivileged operation though, another major thing we
can do is use our control over the unpacking process to do a lot more
sophisticated caching.  We can build up a precise mapping of (rpm
ENVR, file path, selinux label) -> object and avoid rechecksumming
each time.

And even for files that aren't known, we can parallelize commit with
unpacking, etc.  (Ok assuming treecompose-post won't mutate anything).

236a3c46cd Extract a shared internal rpmostree-hif.[ch]
As we start to do more package things, extract common helper functions
around HifContext * that by default operates on the system root.

Some of these bits should go in libhif, but the immediate plan is to
iterate here, then push downwards later.

cf89acb74c (cleanup): Move the refsack and root loading code into libpriv
We had `src/lib` having its own little private library; I wanted to
use some of it inside `src/libpriv`, so let's consistently have all
private utility code in `src/libpriv`.

Closes: https://github.com/projectatomic/rpm-ostree/pull/147

c16058b66a libpriv: Move rpm/hawkey util functions into -rpm-util
`treepkgdiff` no longer describes the function of the file; as a baby
step towards unifying the db and hawkey code, move the functions into
that file.

7b45f13a62 Link lib/ against libpriv/, use it to share sack loading function
On the plus side, we share some code between the library and the
binary now.  On the downside, because `librpmostreepriv.la` is a
noinst library, its code text is duplicated between the shared library
and binary, at least until we either:

 - Have the binary solely use the public shared library (like ostree does)
 - Install `librpmostreepriv.so` to e.g. `/usr/lib64/rpm-ostree/librpmostreepriv.so`
   without the headers being public
