Always use build + use our own allocator functions - Consistent across platforms and will allow some things macros dont and memory checkers these days are smart enough to get decent output anyway - Minimal namespacing with r-prefix, add compatibility macros to system.h for now so we dont have to change the entire codebase for this - Also make rpmutil.h where the declarations and gcc __attribute__ macros are available everywhere

#define xmalloc(_size) rmalloc((_size))
Add rreallocn() to librpmio public API rreallocn() is like realloc() but with multiplication protection. Inspired by glibc's reallocarray() but I dislike that name. While at it, add xmallocn() as a shortcut to rreallocn(NULL, ...) case. Based on initial patch by Demi Marie Obenour.

Reimplement setprogname() and getprogname() to be generic and portable The RPM code contains setprogname()/getprogname() support implemented through compatiblity layer with very old GLIBC (internals supported back to '95 and earlier), before stabilization of the GNU C library. This compatiblity layer (__progname, __assert_progname, setprogname()) is supposed to support well archaic GLIBC, but on the other hand it pollutes the library namespace and introduces unpredicable compillation errors on BSD systems. The functions setprogname() and getprogname() are natively supported in NetBSD and work the same way as __progname from the GNU C library (they are even implemented in the same way - but with a slightly changed logic). The support for very old (20 years and older) GNU C Library is obfuscating the code, because it uses defines over defines without a word of explaination why to do so. It's important to note that the setprogname()/getprogname() was inconstiently implemented in the codebase, duplicating the code and/or functionality. Add new generic functions getprogname() and setprogname() and bind it to: - the current and for two decades stable GNU LIB C implementation, - the current NetBSD implementation (introduces to NetBSD in 2002), - fallback reimplementation functions of the setprogname() and getprogname() functionality for other systems. Don't support anymore old GNU Lib C internals and don't support older NetBSD systems, as they aren't supported for many years. Add to the codebase comments explaining the relevant codeparts.

Actually test for __progname too Hopefully resurrecting whatever got broken by the round of changes surrounding this, __progname is not an entirely glibc/linux thing.
