Remove unused quark arguments all around the matcher code
tests: interpret: Fix build for matcher API change
build: Don't enable pty helper by default
a11y: Remove unused code

The function is always called with 0 quark (since commit
a44035e91dffdbeb3613d56234c74bb6d8483368), so just removed
the parameter.
debug: Improve sequence->string conversion

Print OSC, CSI etc.
matcher: Use less relocations
vteapp: Add back C test application

So you can test vte when building with vala fails.
widget: Immediately resize the ring on app-initiated window resize

table: Remove unused %i support in capability strings
table: Remove support for unused %2, %3, and %M in cap strings
emulation: Fix cursor backward movement

(broken since commit 60c0bca2f00cd55ea1eb42fd59fa017b62197c9d)
caps: Minor
caps: Adjust start-of-string / end-of-string to match xterm

No idea what they are for, but here's a test case:

$ echo -e "\eXas\e\\df

It should only show "df".  Ie, the portion between ESC X and
ESC \\ is skipped.
emulation: Improve the handling of Tab and CJK fragments

Tab is converted to spaces when the content underneath is modified, instead of
when the cursor is moved over. Only the left part is converted to spaces, the
right part becomes a shorter tab.

Double wide characters are replaced by spaces when split in two.
