The purpose of this script is to search your local git repository and use the
change-id information and obtain information about uploaded git commits

This can be helpful when sharing the changes with other people. Obviously
this requires due diligence with the maintenance of Change-Id information in
the git commits.

-c <commit-id>
	Where <commit-id> is a commit id in your local git history (see git log).
	You can also use short cuts like HEAD~3
-p <project>
	The git/gerrit project on the gerrit server
-b <branch>
	The git branch in gerrit
-s <server>
	The gerrit server. It is suggested that you use a server name which is
	configured in your .ssh/config for e.g.:

	Host review.omapzoom.org
	User a0741364
	Port 29418
	PreferredAuthentications publickey
	ProxyCommand /usr/bin/corkscrew wwwgate.ti.com 80 %h %p
-G
	Look at the last few local commits and print out the projects and
	branches.
-f
	Print full gerrit info per commit
-t
	Get fetch information

Example:

Say you have uploaded three commits to gerrit and what to share the review URLs

	changelist.sh -c HEAD~3 -p platform/hardware/ti/omap4xxx -b p-ics-mr1

This will output:

Uploaded commits from: review.omapzoom.org: platform/hardware/ti/omap4xxx: p-ics-mr1

  subject: hwc: changes for blit framebuffers
  url: http://review.omapzoom.org/18950
  subject: hwc: Add some functions to aid debug of Post2() api
  url: http://review.omapzoom.org/19167
  subject: HWC: Simplify RGZ blit interface so HWC does less
  url: http://review.omapzoom.org/18711

Adding the -t option will also show the git fetch commands to obtain the uploaded
patches:

changelist.sh -c HEAD~4 -p platform/hardware/ti/omap4xxx -b p-ics-mr1 -t

  subject: Support BLIT_ALL when S3D is enabled
  url: http://review.omapzoom.org/19202
    git fetch ssh://review.omapzoom.org/platform/hardware/ti/omap4xxx refs/changes/02/19202/3 && git cherry-pick FETCH_HEAD
  subject: HWC: Simplify RGZ blit interface so HWC does less
  url: http://review.omapzoom.org/18711
    git fetch ssh://review.omapzoom.org/platform/hardware/ti/omap4xxx refs/changes/11/18711/5 && git cherry-pick FETCH_HEAD
  subject: hwc: Add some functions to aid debug of Post2() api
  url: http://review.omapzoom.org/19167
    git fetch ssh://review.omapzoom.org/platform/hardware/ti/omap4xxx refs/changes/67/19167/4 && git cherry-pick FETCH_HEAD
  subject: hwc: changes for blit framebuffers
  url: http://review.omapzoom.org/18950
    git fetch ssh://review.omapzoom.org/platform/hardware/ti/omap4xxx refs/changes/50/18950/8 && git cherry-pick FETCH_HEAD
