Correctly detect the presence of the Adobe specific APP14 JPEG marker (bug 1140761)
...
According to the specification, http://partners.adobe.com/public/developer/en/ps/sdk/5116.DCT_Filter.pdf#G3.851943 , the content of the marker segment should begin with `Adobe`, and not `Adobe\x00` as the code currently look for.
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1140761 .
Fixes the colour conversion part of issues 4090 and 5623.

Optimize JPG.js receiveAndExtend for 1 bit case.
...
Profiling showed that receiveAndExtend is frequently called with the length of
one bit. This happens for example in decodeBaseline.
For a single bit, the loop and shift in receive, as well as the shifts in
receiveAndExtend are overhead.
This shortcut manually calculates the shifts by either returning 1 or -1 from
receiveAndExtend by reading the bit and deciding on the return value.
While it comes with an overhead for each non-one length, the speedup is at about
10% in the hot parse/decode path.

Optimized loops in JPG conversion.
...
This change makes the 4 conversion loops look the same.
It optimizes access of the array length and access of the property
numComponents, which is known to be constant.
