We want PV values to be easily ordered, so
use the latest entry in build-compare.changes which
will also match the date of SRCREV.

Replace some "+=/=+" with "=" when setting BBCLASSEXTEND, they are
redundant and inconsistent with the same setting in other recipes.

Currently, PV is "git" and contains no version information.

* The deb and ipk's depends version string is like:
Depends: libc6 (>= 2.24)
Update trim_release_old and trim_release_new to match the bracket in
the end ")".
* The deb's data tarball now is .tar.xz, and ipk's is .tar.gz.
* Update adjust_controlfile() to make ituse trim_release_old and
trim_release_new.

The rpm tool is a heavy process, pkg-diff.sh ran 16 (or 17 for kernel)
"rpm -qp" times when the pkgs are identical, now we only run
"rpm -qp --qf <all we need>" twice (one is for old pkg, and one is for
new), save the results to spec_old and spec_new, then use sed command to
get what we need later, this can make it 75% faster when the pkgs are
identical. Here is the rough data on my host Ubuntu 14.04.4, 32 cores
CPU and 128G mem:
* When the pkgs are identical:
- Before the patch: 1s
- After the patch: 0.26s
I compare the whole spec firstly, and return 0 if they are the same,
or go on checking one by one if not, without this, it would be 0.46s,
the gain is great when there are lot of packages, usually, we have
more than 10,000 rpms to compare.
* When the pkgs are different:
That depends on where is the different, if the different is at the
comparing rpmtags stage:
- Before the patch: 0.26s
- After the patch: 0.29s
Increased 0.03s, but if the different is happend later than comparing
rpmtags, it will save time.

The command like:
rpm -qp --nodigest --nosignature --qf '<foo> [%{REQUIRENAME}\n]\n'
^^space
The space will be printed, and will impact the check result, so remove it.

We don't need PATCHTOOL to be set to git in this recipe, and setting it
that way requires that the running user has git user & email configured,
which on a build server it might well not be.

This is just rudimentary support at the moment as we'd potentially want
to compare the control files a bit more specifically than this does, but
it's a start.

The patch can't be applied by "git am -3" with newer version of git
(such as 2.0.1), and can't be applied by "git am/apply" with any
version, now fix it

The description for build-compare describes it as "This package contains
scripts to find out if the build result differs to a former build." More
specifically this contains a script that will display differences between
"packages." It works with rpms, tarballs and other various types of
packages.
The idea is that it will eventually be used in Yocto to check for differences
between sstate so that we can check for build reproducibility. It will
also be used once an updateable sdk is in place, so that packages that
have different hashes but are not different in contents, don't get updated.
It could also be used in the same manner when updating packages from a
package feed.
