Implement true color support define in:
https://en.wikipedia.org/wiki/ANSI_escape_code
The sequence is:
ESC[ … 38;2;;; … m Select RGB foreground color
ESC[ … 48;2;;; … m Select RGB background color
This field was used during development to measure the
coverage of the ANSI terminal parser against typical
terminal input sequences.
The "handled" field has not been read by any code since
commit 1ee54cd7 (February 2011). Eliminating the field
by popular request (closes#723).
* 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
terminalfunctions.cc: set_if_available() was undeclared.
Fix printf() wint_t/wchar_t warnings.
mosh-server.cc: Fix warning for side effects inside typeid().

This helps to catch unused functions like the former mosh_read_line,
allows the compiler to make better inlining decisions, and reduces the
binary size a bit.
