* get rid of extra memory duplication;
* support of recursive search of correct encoding;
* add tests.
Signed-off-by: Andrew Borodin <aborodin@vmail.ru>
Remove tests whose results are not used:
* AC_CHECK_HEADERS of unistd.h, fcntl.h, sys/time.h, sys/types.h
* AC_HEADER_MAJOR
* AC_HEADER_TIME
* AC_HEADER_DIRENT
* AC_CHECK_FUNCS of isascii, statfs, sysconf, tcgetattr, tcsetattr, ftruncate
* AC_FUNC_STRCOLL
AC_C_CONST is obsolete, today it is safe to assume all C compilers
support at least C89.
The INTERACTIVE UNIX that needed AC_ISC_POSIX is long dead.

* 2988_ignore_unknown_esc_sequences:
When we see an unknown sequence, it is not enough to drop already received part - there can be more of it coming over e.g. a serial line.
This change prevents misinterpreting an unknown ESC sequence's tail as a garbage input. To reproduce, run "sleep 3" and hold down Down_Arrow key until sleep runs. With debugging log enabled, the following can be seen:
Ticket #2988: When an unknown key is pressed, it is interpreted as garbage.
to drop already received part - there can be more of it
coming over e.g. a serial line.
To prevent interpreting it as a random garbage,
eat and discard all chars that follow.
Small, but non-zero timeout is needed to reconnect
escape sequence split up by a serial line.
Before this change, Ctrl-Alt-Shift-Right_Arrow generates "1;8C"
bogus "input" in MC on my machine; after the change,
nothing is generated.

With this patch, no bogus "input" is generated.
Longer unknown sequences need an additional fix, coming next.

keyboard input: simplify code, no logic changes
This change slightly simplifies and rearranges the code
in get_key_code(), reduces indentation levels there,
adds a few comments. The logic remains the same.
This is a preparatory patch for subsequent changes.
