Charlie Gordon 494e9f7866 include cflags.mk for extra gcc warnings if present
utf8_encode now returns the number of characters copied,
  simplified code accordingly
made local functions static
tagged unused function arguments
fixed shadowing issues
added support for GCC attributes for unused arguments and format strings
use snprintf() instead of sprintf()
moved scattered declarations to qe.h
removed duplicate declarations in header files
eb_write() payload argument is now const
fixed crash bug: reset trace_buffer upon deletion
improved trace_buffer readability: trace all pseudo tty streams separately
added missing structure initializers
removed buffered string handling from cutils.h
added new buffered string API for statically allocated buffers (should unify)
small improvements in X11 initialization
improved consistency in tty.c (function names...)
  added STDIN and STDOUT streams in QEditScreen to stop using stdin and stdout
  use unlocked stream I/O if available (faster)
  changed and documented terminal setup and exit sequences
  improved charset handling
mode_line functions now return the character count (like snprintf)
