3842ca4db5 Add a separate simple internal base allocator and remove base_arena, so that
there is never any need to recursively call the main allocation functions.

Remove recursive spinlock support, since it is no longer needed.

Allow chunks to be as small as the page size.

Correctly propagate OOM errors from arena_new().

707ca316b6 Define NO_TLS on ia64. The dynamic TLS implementation on ia64 is
broken for non-threaded shared processes in that __tls_get_addr()
assumes the thread pointer is always initialized. This is not the
case. When arenas_map is referenced in choose_arena() and it is
defined as a thread-local variable, it will result in a SIGSEGV.

PR: ia64/91846 (describes the TLS/ia64 bug).

52828c0e9c In preparation for a new malloc implementation:
* Add posix_memalign().

  * Move calloc() from calloc.c to malloc.c.  Add a calloc() implementation in
    rtld-elf in order to make the loader happy (even though calloc() isn't
    used in rtld-elf).

  * Add _malloc_prefork() and _malloc_postfork(), and use them instead of
    directly manipulating __malloc_lock.

257551c6a0 Add a64l(), l64a(), and l64a_r() XSI extentions. These functions convert
between a 32-bit integer and a radix-64 ASCII string.  The l64a_r() function
is a NetBSD addition.

a617a18a23 Fix ptsname(3) by converting it to use devname(3) to obtain the name of
a tty device instead of the legacy minor number approach.  This is known to
fix gnome-vfs' sftp module as well as kio_sftp and kdesu on -CURRENT.

Thanks to scottl for the snprintf() approach idea.

2dcb9ce484 Remove the check about whether MALLOC_EXTRA_SANITY is defined,
surrounding the undef'ing it.  It does not seem necessary to
undef some symbol that is not exist, and gcc does not complain
about whether a symbol is exist before #undef'ing it out.

2571c7f720 POSIX says that 0[xX] prefix is _optional_ even in base 16 case, make it
really so.

"If the value of base is 16, the characters 0x or 0X may optionally
precede the sequence of letters and digits, following the sign if
present."

dfcc91e219 sranddev() is not magic pixie dust. While it gives a good random
seed, the random number generator rand(3) still sucks and is unlikely
sufficient for crypto use.  Correct what appears to be a cut and paste
error from the srandomdev() man page.
