LU-177 jenkins build enhancements

From fd0bd149e66cbc06a17c372e159f9bfba024cc97:
  b=22281 refactor packaging and versioning

  Only the --enable-dist configure flag.

  i=wangyb
  i=mjmac

From ae4652c1ac831912e186d10214b266b994d7a7e2:
  b=24090 distro and target autodetection

  Automatically detect the target and distro.  It's in fact a little
  crazy that these are two separate options.  They should be merged.

  i=cliff
  i=minh

From 63520d0a8089ba4929fc6767442e85bde4a1ccad:
  b=24091 find_linux_rpms utility

  Write a utility to find the the kernel "devel" package needed.
  Restructure some code to facilitate reuse of existing code to
  use in the utility.

From 2941269c348cfed9c22d02c45eb00687339adaaa:
  LU-120 the perfect storm

  There is a corner case in the debian patching/unpatching process
  where a patch converts the use of a given file to a file.in that is
  to be substed.  The problem is that between the configure and the
  make debs, a file, which a debian patch wants to remove already
  exists (it was created by the configure) and dpkg-buildpackage's
  unpatch step fails becuase it wants to try to create a file which
  configure already created.

  LU-73 lbuild and friends for jenkins

  Add the portions of this patch needed for lbuild to work in
  our matrix-building jenkins environment.
  Included is a re-org of the RHEL5 lbuild code to maximize code
  reuse and minimze code replication for future RHEL6 landing.
