Compatibility fixes in reallocarr(3)

Make this work on !NetBSD platforms:
- replace __CTASSERT() with platform agnostic solution SQRT_SIZE_MAX
- include nbtool_config.h for cross builds to get definition of __RCSID()
- restore errno in the last rare code path for platforms affecting errno(2)
in memcpy(2)

While there: rename parameter name 'num' to 'number' to be in sync with
the calloc(3) parameter naming.

# 1.3 19-Feb-2015 wiz

Add EXAMPLES section, from Youri Mouton.
Bump date.


# 1.2 18-Feb-2015 wiz

Fix Xref. Split line, Ox doesn't take word arguments.


# 1.1 17-Feb-2015 joerg

Introduce reallocarr(3) for easy (re)allocation of memory with overflow
checks. Compared to OpenBSD's reallocarray, makes it easier to avoid memory
leaks on allocation failures and it doesn't depend on malloc(0) != NULL
for correct error checking. Compared to plain realloc, it also avoids
the problem of intermediate integer overflows. The trade-off is the use
of void * to side step C type system with regard to generic pointer to
pointer.
