Tim pointed out that 443b5814ee77f8c9083079ce0e6a0806e087630f broke the parsing
of backport versions, such as 8.13~14.10+ppa.1. This should fix it. I used the
following script to validate the regular expressions:

dannf@fluid:~$ cat test.sh

set -e

splitver() {
    local ver="$1"
    local abinum="$(echo $ver | sed -r -e 's/([^\+~]*)\.[^\.]+(~.*)?(\+.*)?$/\1/')"
    local uploadnum="$(echo $ver | sed -r -e 's/[^\+~]*\.([^\.~]+)(~.*)?(\+.*)?$/\1/')"

    echo "$abinum $uploadnum"
}

do_test() {
    local ver="$1"
    local expected="$2"

    local actual="$(splitver $ver)"

    if [ "$actual" = "$expected" ]; then
	echo "PASS: $ver"
	return 0
    fi
    echo "FAIL: $ver split as $actual"
    return 1
}

do_test "33.58" "33 58"

TLDR; This changes the way that version strings are parsed in the packaging to
make it easier for me to maintain topic branches/PPA builds. There should
be no changes to how things work today for standard Ubuntu kernels. But,
it allows for topic-branch maintainers to add an optional ".X" in the ABI
name, for reasons described below.

<Regression Testing>
------------------
Old Parsing:
  = abinum =
  $ echo "33.58" | sed -e 's/\..*//'
  33
  = uploadnum =
  $ echo "33.58" | sed -e 's/.*\.//'
  58
  = abi =
  $ echo "33.58" | gawk -F. '{print $1}'
  33

New Parsing:
  = abinum =
  $ echo "33.58" | sed -r -e 's/([^\+]*)\.[^\.]+(\+.*)?$/\1/'
  33
  = uploadnum =
  $ echo "33.58" | sed -r -e 's/[^\+]*\.([^\.]+(\+.*)?$$)/\1/'
  58
  = abi =
  $ echo "33.58" | sed -r -e 's/([^\+]*)\.[^\.]+(\+.*)?$/\1/'
  33
</Regression Testing>

When maintaining topic customizations that track Ubuntu kernel releases, it
is nice have the following features:

 1) Ability to decipher the base Ubuntu kernel revision used from the topic
    kernel's revision number
 2) Use a version that dpkg sorts > the base Ubuntu version
 3) Use a version that dpkg sorts < the next expected Ubuntu version
 4) Ability to retains the same ABI as the base Ubuntu version when the
    ABI has indeed not changed. This helps with e.g. d-i compatibility.
 5) Make use of ABI tracking facilities (vs. just disabling them)

This is difficult to do with the current version scheme, which encodes the
ABI number in the version string:

  <upstream-version>-<abi>.<rev>

I can tack a "+topic.<N>" to the end of rev, we can solve 1-3, but only as
long as as the ABI is the same. Once the ABI changes, I don't have a good way
to bump it. If I increment the ABI, we'll overlap with the next Ubuntu ABI
(breaking #4). If we jump to a huge ABI number (e.g. x100 to go from 32 to
3200), we'll have a package revision that will never again upgrade to an Ubuntu
version (breaking #3), and never get back to the Ubuntu ABI (again breaking #4).
I can of course use a linux-meta package to e.g. transition from a 3200 ABI back
to a 32 ABI at the packaging level, but the bootloader will still consider
3200 to be newer and therefore the default.

I've therefore started using the following scheme:

  <upstream-version>-<abi>(.topicabi)?.<rev>(+<topic>.<topicrev>)?

Where topicabi must always be >= <rev> (ugly, but necessary).

If I don't break the ABI, I can then branch and return like so:

3.16.0-8.6 -------------------------------------------------> 3.16.0-8.7
   \                                                             ^
    \                                                            |
     \--> 3.16.0-8.6+topic.1 -------> 3.16.0-8.6+topic.2 --------/

If I do need to break the ABI, I can branch and return like so:

3.16.0-8.6 -------------------------------------------------> 3.16.0-9.1
   \                                                             ^
    \       ABI break #1                   ABI break #2          |
     \--> 3.16.0-8.6.6+topic.1 -------> 3.16.0-8.7.6+topic.2 ----/

When the symlinks are made we attempt to use relative links if that
would work.  However this relies on the file we are making the link to to
actually exist.  When it does not we fall back to absolute.  This impacts
the initrd links which are made before we make the initrd itself.

When the caller has asked us to use a specific handle file and that file
does not yet exist, see if there are any other files we can use in that
directory.  In the common case this will be a version specific file and
highly unique.

If we do not supply an installation prefix when we are building perf
it will assume it is designed to run relative to the builders HOME.
This means that as built on a buildd we will check for the system
configuration relative to the buildd users home rather than in /etc.
This implies a local user could use this to compromise other users _if_
there is a buildd user installed on the system and they have access to it.
