Paul Eggleton - March 27, 2013, 6:05 p.m.
Collect SRCREV information in a separate task and write it out in a
format which is more consistent with the rest of the buildhistory
output. Using a task means that SRCREV values will also be recorded for
native recipes and not just target ones, and the new formatting also
correctly handles multiple entries in SRC_URI.

Also adds scripts/buildhistory-collect-srcrevs which will report on all
of the recorded SRCREV values in a format suitable for use in global
configuration (e.g. local.conf or a distro inc file) to override AUTOREV
values to a fixed set of revisions. Example output:

 # emenlow-poky-linux
 SRCREV_machine_pn-linux-yocto = "b5c37fe6e24eec194bb29d22fdd55d73bcc709bf"
 SRCREV_emgd_pn-linux-yocto = "caea08c988e0f41103bbe18eafca20348f95da02"
 SRCREV_meta_pn-linux-yocto = "c2ed0f16fdec628242a682897d5d86df4547cf24"
 # core2-poky-linux
 SRCREV_pn-kmod = "62081c0f68905b22f375156d4532fd37fa5c8d33"
 SRCREV_pn-blktrace = "d6918c8832793b4205ed3bfede78c2f915c23385"
 SRCREV_pn-opkg = "649"

Some notes on using this script:
* By default only values where the SRCREV was not hardcoded (usually
  i.e. AUTOREV was used) are reported - use the -a option to see all
  SRCREV values.
* The output statements may not have any effect in the face of overrides
  applied elsewhere; use the -f option to add the forcevariable override
  to each output line to work around this.
* The script does not do any special handling for multiple machines;
  however it does place a comment before each set of values specifying
  which triplet they belong to as shown above.

Relates to [YOCTO #3041].
