227fe5fc92 Use backtrace in crash handler on POSIX platforms
Non-ancient versions of GCC and clang should ship it, and in contrast
to the <execinfo.h> backtrace_symbols() it also works with
-fvisibility=hidden

64b21fcd0c Add Posix_GetExePath() function
I'm gonna use it with libbacktrace - I'll need the path of the
executable before I can use idStr (and thus before I could call
Sys_GetPath(PATH_EXE, str)).

430a8f5e95 POSIX: Show errormessage if loading a (Mod) .so failed, refs #318
.. but only if the file exists.
It's ok if mods don't have their own DLL/.so, but if they do have one
and loading fails it's interesting why they failed (e.g. no access
rights, 64bit lib with 32bit executable or other way around, missing
symbols due to wrong libc version, ...)

The same should be done for Windows, but that's still TODO.

1320e29aaf Implement Signal-Handlers for POSIX systems, incl. SIGTTIN/SIGTTOU
handling SIGTTIN/OU allows running Doom3 in the background (or even
sending it to the background with Ctrl-Z + bg) by disabling TTY input
(before it would get stuck when run in background without +set in_tty 0,
 see #215)

While at it, I also added signal handlers for some common crash signals
(SIGILL, SIGABRT, SIGFPE, SIGSEGV) to print a backtrace before exiting
the game (partly based on Yamagi Quake II code).

bbcb2b00dc Fix endless loop with in_tty on selected archs
Ran into this on aarch64.

befe732dbb Fix new[]/delete missmatches and memory leaks found by clang's ASAN
Sometimes memory was allocated with new[] but freed with delete instead
of delete[], which is wrong.
And there were some small memory leaks, too.
Furtunately clang's AddressSanitizer detected all that so I could easily
fix it.

(There seem to be some more small memory leaks which are harder to fix,
though)

5c99ff4657 make "./dhewm3 +set in_tty 0" actually work
the problem was that the CVar was initialized from the commandline
*after* Posix_InitConsoleInput() is called, so it was too late.
common->StartupVariable() seems to be the right way to initialize a
CVar early.

5a9c2006ff Get rid of Posix_EarlyInit() and Posix_LateInit()
Since we don't have our own signal handler anymore, those two
init functions can be merged into the existing Sys_Init(), which
is already called by common->Init().

0ccef1eba8 Get rid of Sys_FPU_GetState()
This was only implemented with MSVC style asm.
Comments suggest that it was used to help catch invalid FOV calculations,

79aea4082f Port Linux events to SDL
New CVar "in_kbd" to set the layout for the keyboard. SDL 1.2
doesn't offer any way to determine it, and we need this feature
to use the same key for toggling the console independent of the
keyboard layout.
The old "in_nograb" from the Linux backend is still supported.

736ec20d4d Untangle the epic precompiled.h mess
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
