* Cosmetic code changes.

CRLF format.

the DOS/conio.h driver, and updated the unicode test accordingly.

equivalents in CP437 0x7f - 0xff are translated.

* Use RETSIGTYPE for signal handler return values.

in the SLang driver.
  * Cosmetic fixes in configure.ac.

* Got rid of static buffers; we now use cucul_free() to free exported
    buffers.
  * Fixed light background in the ANSI exporter by adding escape sequences for
    most terminal emulators.
