* 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

This commit is somewhat subtle; it informs Coverity that
Parser::Transition only holds an Action* temporarily, and should never
create/delete one. I believe runtime checkers should also understand
this OK.

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.

This function is buggy. feof(file) does not become true until after
we’ve tried to read past the last character; it should instead be
checking the getc return value for EOF (which is distinct from any
unsigned char). Really it should just be replaced by istream
&std::getline(istream &is, string &str). Fortunately, it’s unused so
we can just delete it.
Resolves a truncated stdio return value issue found by Coverity Scan
service.

size_t is unsigned. Fixes two issues found by the Coverity Scan
service, one about the dead code and one about the std::string
exception being uncaught by mosh-server.

This refactors out a very common pattern of formatting "%s: %s" with
e.function.c_str() and strerror( e.the_errno ) into just the what()
method of NetworkException. It's also a prerequisite for making cleaner
public API for any exceptions we throw, and allows us to more easily
get exceptions passed back to us to handle.
I do sympathize with the motivation for these trailing commas, but
they cause silly build failures with --enable-compile-warnings=error
(which is used at least by the Debian/Ubuntu package).
