This commit changes the sysroot API so that one can create arbitrary
new deployment checkouts, then commit them as one step. This is to
enable things like an automatic bisection tool which say create 50
deployments at once, then when done clean them up.
This also moves some printfs from the library into src/ostree.
This uses gpgv for verification against DATADIR/ostree/pubring.gpg by
default. The keyring can be overridden by specifying OSTREE_GPG_HOME.
Add a unit test for commit signing with gpg key and verifying on pull;
to implement this we ship a test GPG key generated with no password
for Ostree Tester <test@test.com>.
Change all of the existing tests to disable GPG verification.
The actual deployment checksum shouldn't be in there, because we may
just swap bootlinks, rendering the name of the old bootloader entry
file invalid. Thankfully nothing actually parsed the names of these
files, so let's just use the index.
libtest.sh has an setup_os_repository() helper function tha is
used by many tests to setup an OSTree initial repository.
This function creates an syslinux configuration unconditionally
but OSTree supports other bootloader backends besides syslinux.
So, is better to conditionally create a syslinux configuration
only when it is needed.

Before, we were writing the "bootversion", which is either 0 or 1, for
all entries. This is completely wrong; the idea of the "version"
field is to compare between entries.
Fix this by writing out the inverted index - internally, index 0 is
the *first* boot entry, so we give it the highest version number, and
index N is the last, so give it version 0.
Then fix the deployment sorting code to correctly reverse the version
number comparison, so we read back the right order.
In practice before this bug didn't matter because "normally" you only
have at most two deployments.

Otherwise it's really easy to keep accumulating deployments. Also, we
may want to run this after rebooting, so we're back down to one
operating system.
