Fix UHCI Short Packet Transfers
Add avrdude package (with dependencies)

I confirmed that Akshay's patch to UHCI gets avrdude working with the
usbasp programmer.
Fix the test_app_server build.
Simple test harness for app_server tests

This was developped for the transformations test, but can be used for
other tests too. Extract the relevant classes to a separate file.
Add a test for radial gradients.

* This shows that the radius is ignored and all gradients are drwan with
a radius of 100.
Draw radial gradients using the proper radius.
Add a package for lynx

It's mostly because I need it for irssi docs.
Guard header for use by assembler code

Somehow it ends up being used by shell.S for the verdex bootstrap.
Add asciidoc and tig package
Add testcase from #2946.
More test cases for gradients with alpha channel

* Swapping the opaque and transparent ends leads to different results,
* Linear gradients are also affected.
Tracker: Remove logically dead code

Replace with an ASSERT that srcWindow != NULL by the time we've gotten
this far.

CID 1228649 and CID 1228650
Add a gcc2 version of libffi
glib2: updated package (fixed glib-gettextize)
Runtime loader: Fix unchecked return value

Tested by running Attraction! from haikuware.com

CID 1228648
tty: Add bitmask ioctls TIOCMBIS and TIOCMBIC

Equivalent to TIOCMSET + bitmask + TIOCMGET but with a single call.

Gnokii uses that.
tty: Don't ignore errors when setting DTR

Instead we and the return value of both calls.

So if any fails we return an error.
Bump revisions of gcc_x86 & haikuwebkit for gcc2h.

This will pull in the requirement for a newer haiku
revision, as the fix to WebPositive lies in haiku,
not haikuwebkit.
