Add another round-trip verification. For both original and generated
state, generate a diff from an initial, empty state. Verify that
these two diffs are the same.
The problem was that the round-trip verification code copies the
current state, which may contain intermediate Parser state for
multibyte characters and ANSI escape sequences. It then applies diffs
to that copy, which may appear as badly formed input.
Also removes some dead, never-used code.
ASCII <-> UTF has trivial mappings. Avoid wcrtomb() and mbrtowc().
ISO-8859-1 is all narrow characters, and cheap to test for. It might
be possible to cheaply test other popular UTF blocks and/or planes as
well.
These two changes get 2-3x faster input processing on Linux and
FreeBSD. Performance improvement in actual usage is more modest but
still significant.
* Refactor put_cell() and parts of new_frame(), and associated state, into put_row().
* Optimize display and line wrap handling code/output.
* Make last_frame a const ref, to eliminate a costly copy of the framebuffer on every screen refresh.
* In new_frame()'s scroll optimization, don't copy rows, use pointers instead.
* Don't check entire frame buffer for scrolling if first line hasn't scrolled.
* Add a generation counter on Row objects to allow quicker/better identification of scroll regions
* Use at() for bounds-checking on framebuffers, because they can be resized.
* Copy and resize scroll buffer on window resize.
* Reduce the size of Terminal::Cell.
* Change colors and attributes in Terminal::Rendition to bitfields/bitmask.
* Change Cells to use UTF-8 strings instead of vector<wchar_t>. Store Rows in a vector instead of a deque.
* Add various Framebuffer::append() methods for more efficient passing of single and repeated characters.
* Change title/icon strings from deques to a vector typedef-- this is more for tidiness than any real performance.
* Fix inefficient STL use around Parser::UTF8Parser.
* Reduce typeid() usage, change some of it to a virtual method
* Do multiple-line scrolls as a single move

Remove bad automake dependency causing double execution.
Properly update the version in the non-Git case.
Git commands are now in a condition-expression, won't break build.
Test that we're in repo root (i.e., our own and not somebody else's).
Do `git describe --always` to handle shallow Git clones.

This improves the completion, as suggested in
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=782169>,
and moves the completion from `/etc/bash_completion.d/mosh` to
`/usr/share/bash-completion/completions/mosh` as recommended by
lintian in its `package-install-into-obsolete-dir` check.
Closes#628.
