Always start a sentence with lowercase letter after 'Note:', 'Warning:',
etc. This unifies all occurrences.
No functional change.

"config.h" is a locally generated header. It must be included as
'#include "config.h"'.
It is already included correctly in some sources files. This commit
unifies the way how "config.h" is included.

Except for the added (and sorted) includes, the removal of redundant
parentheses, a few cases that have been refactored for readability, and
a couple of non-string cases that I've left out of the change, this
patch can be approximated with the following semantic patch:
$ cat ~/tmp/spatch/streq.sp

'endptr' is appropriate internally in strtol(3) because it's a pointer
to 'end', and 'end' itself is a pointer to one-after-the-last character
of the numeric string. In other words,
endptr == &end
However, naming the pointer whose address we pass to strtol(3)'s
'endptr' feels wrong, and causes me trouble while parsing the code; I
need to double check the number of dereferences, because something feels
wrong in my head.

- Set errno = 0 before the call. Otherwise, it may contain anything.
- ERANGE is not the only possible errno value of these functions. They
can also set it to EINVAL.
- Any errno value after these calls is bad; just compare against 0.
- Don't check for the return value; just errno. This function is
guaranteed to not modify errno on success (POSIX).
- Check endptr == str, which may or may not set EINVAL.

The multiplication was already invoking UB. The test was flawed.
Use __builtin_mul_overflow() instead.

strtol(3) doesn't specify a return value if (value == endptr).
It is always an error, if (value==endptr).

This patch implicitly adds the safety of SIZEOF_ARRAY(), since the calls
were using sizeof() instead.

The separation was unnecessary, and caused build problems. Let's go
wild and obliterate the library. The files are moved to libshadow.
Scripted change:
$ find libmisc/ -type f \
| grep '\.[chy]$' \
| xargs mv -t lib;
Plus updating the Makefile and other references. While at it, I've
sorted the sources lists.
