Subject: toaster: reserve HEAD from imported layers
From: "Reyna, David" <david.reyna@windriver.com>
X-Patchwork-Id: 144163
Message-Id: <1505431229-5404-1-git-send-email-david.reyna@windriver.com>

From: David Reyna <David.Reyna@windriver.com>

The HEAD reference in Toaster layers are reserved for the
"Local Yocto Project" layers, stored at the top directory.
Imported layers are not allowed to use this since they are
managed differently - for example the 'remotes' will collide.

Fix the add layer handler to not drop the data fields when it
is a git repo.

Explicitly inform the user when an internal Toaster error is
returned via AJAX, so that they know why clicking the layer add
button did not do anything.

[YOCTO #9924]
