a definition of a modifiable object with static storage duration, and shall
not contain a reference to an identifier with internal linkage."

As standard does not require compiler to determine when it is safe to
reference an internal function in an external inline function, but instead
delegalizes such reference as a whole, gcc throws a warning for such code
under C99 compilation.  Warning produced by libc header is inhereted widely
and strips the option of using -Werror to track code sanity.

Replace static inline specifier with gnu89 extern inline. Latter "is used
only for inlining. In no case is the function compiled on its own", which
is slightly different from former semantically, but should produce the same
result here.

Add better free tracking.

Included in this change:

- Change the tag when a pointer is freed so it's easy to detect if
  an already freed pointer is being used.
- Move the free backtrace out of the header. This backtrace is only
  used under only some circumstances, so no need to allocate space
  in all headers for it.
- Add new option free_track_backtrace_num_frames to specify how many
  frames to record when the free occurs. This removes the dependency
  on the backtrace option to get backtraces.
