Fixes the following error with musl libc:
src/trap.c: In function 'traphandler':
src/trap.c:178:3: error: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Werror=format=]
snprintf(tmpbuf, sizeof(tmpbuf), "Register dump [%d]: ", NGREG);

There are no standard that says that __WORDSIZE should be defined or
in what include file. So in case its not defined we fallback to a
POSIX compliant way to determine wordsize.
This fixes build with 64 bit musl libc.
See https://tvheadend.org/issues/1983
Use the gcc specific __GNUC__ and __GNUC__ minor to determine gcc version
rather than using the GNU libc specific __GNUC_PREREQ.
This fixes the following compile error with musl libc:
src/descrambler/capmt.c:79:18: error: missing binary operator before token "("
#if __GNUC_PREREQ(4, 3)
^
Rather than check for specific glibc version on PLATFORM_LINUX, check
the existance of qsort_r.
This fixes the following compile error with musl libc:
CC src/main.o
In file included from src/main.c:39:0:
src/tvheadend.h:608:20: error: missing binary operator before token "("
#if !__GLIBC_PREREQ(2,8)

I've removed some of the bounds checking, not a bad thing to have it, but
in general we work on the principle that if the user really is trying hard
enough to pass broken values, then so be it!
Also correct some spelling mistakes and change UI refs to "Unicable" rather
than the standard "EN50494".
