23b2e3cd80 Fix another integer overflow issue discovered by Maksymilian Arciemowicz. 
On top of this, limit the range of getnumber to 0x00ffffff to make sure
that adding two of them does not cause an integer overflow.

c3e906d7a0 There's no need to do the mutex_trylock dance anymore in __cxa_finalize(), 
just using mutex_lock() is enough.

95157b046e Make the atexit mutex recursive and initialize it in __libc_init() 
as suggested by ad@, based on the patch provided by Sverre Froyen
in lib/37654.

Reviewed by ad@ and jmcneill@.

8b96cb8a97 Back out the per-cpu arena changes. With this, ld.so magically stops 
loading libc/libpthread twice -- which does not make sense, because it
has its own private malloc().

f6cecc05cf Sync phk malloc.c with the latest one from FreeBSD. This gives us the 
same api as jemalloc by:

    - adding posix_memalign()
    - moving calloc in the same file
    - renaming malloc_options -> _malloc_options

46de085339 Revert the CSE parts of the previous change. "run" is calculated with 
a different value for "pageind" each time through the loop, so we can't
precalculate it.

7ed9cc8edd On sparc64, both __sparc__ and __sparc64__ is defined. Avoid redefinition 
of size constants for sparc64.

This code still produces many, many lint warnings due to "may loose accuracy"
when mixing long/int, and also warnings related to <<.

3a6ef3e3c1 Keep track of atexit functions that are added while processing 
atexit functions, to ensure that the new functions will be called.

af220472c9 Ensure that the struct atexit_handler has been removed from the list 
of pending atexit handlers before the structure is reused.  This prevents
__cxa_finalize from going into an infinite loop when an atexit handler
register a new atexit handler as in:

   #include <stdlib.h>

   void two(void) {
   }

   void one(void) {
           atexit(two);
   }

   int main(void) {
           atexit(one);
           return 0;
   }

15b661abe9 Fix several end cases: 
o If a long option looks like an ambiguous abbreviation of two or more long
  options, but all the possible interpretations would return the same
  value, then just return that value without complaining that it's
  ambiguous.

o If a long option could be interpreted either as an exact match for one
  long option, or as an abbreviation for one or more other long options,
  then treat it as the exact match.

These changes align NetBSD's getopt_long(3) with the current behavior of
GNU getopt_long(3), the de facto standard, and FreeBSD's getopt_long(3).

a3ae2738c9 Document that getopt_long(3) can and will accept unique abbreviated long 
option names.  This feature has been present since getopt_long(3) was first
released in NetBSD 1.5.  This is also standard GNU getopt_long(3) behavior.
