It's seems people still follow old advices for SSD/4K devices. Let's
make CHS deprecation more visible at the begin of the man page...

It seems coverity and clag have no clue about relation between argv[]
and argc. Let's make code more readable for them...

We usually check lookup() return value. Let's do it in this case too.
It seems static analyzers will be happy with consistent code.

The ttyname(3) can fail to access /dev/ path, and that will cause function
to fail without setting errno value with result of rather confusing error
message. Lets start setting stdin permission via /proc when this happens as
a go-around, with hope kernel following symlink does not fail. Ok, noted,
that hopes of symlink follow working are pretty slim.
Based on patch from Sami Kerola <kerolasa@iki.fi>.

This started as fix to following warning.
libblkid/src/superblocks/bcache.c:33:3: warning: ISO C99 doesn’t
support unnamed structs/unions [-Wc99-c11-compat]
But when sent to review Karel told out rather than getting rid of warnings
lets get rid of everything unnecessary.
[kzak@redhat.com: - use original struct member names rather than 'padN']

This fixes following warning about deprecatd __FUNCTION__ that is another
name for __func__ since GCC (pre 2.95, released July 1999).

‘__FUNCTION__’ predefined identifier [-Wpedantic]

* call strchr() only once
* avoid things like strcat(buf, strchr(dir, '*') + 1)
* make it more readable

The self_pte() can return NULL if partitions array is not large enough,
but that should also be impossible and definitely a bug.

Let's keep compilers and static analyzers happy. The idea is to use
memcpy() to copy from buffer to variable and use all label as unsigned
char rather than vectorize by unsigned short.

The __has macros are more portable (supported by gcc as well as
clang).
The old __GNUC_PREREQ is deprecated and it should be removed in
future. (Well, the __has macros are supported since gcc 5, so we
should be patient as some old stable distros (e.g. RHEL 7) use gcc
4.x).
This patch helps clang to correctly analyze our xalloc.h stuff.
