f26da23003 Make the 'C' and 'c' malloc options consistent with other options; 'C'
doubles the cache size, and 'c' halves the cache size.

cd2c530a43 In arena_chunk_reg_alloc(), try to avoid touching the last page in the
chunk during initialization, in order to avoid physically backing the
page unless data are allocated there.

cc036a2601 Use uintptr_t rather than size_t when casting pointers to integers. Also,
fix the few remaining casting style(9) errors that remained after the
functional change.

92d4e46d35 Revert addtion of assertions in revision 1.99. These assertions cause
problems in cases where regions are faked up for the purposes of red-black
tree searches, since those faked region headers reside on the stack, rather
than in a malloc chunk.

internal allocation does not rely on recursive arena use (base_arena was

2622b7ee77 Return NULL if there is an OOM error during initialization, rather than
allowing the error to be fatal.

Move a label in order to make sure to properly handle errors in malloc(0).

4179e6a903 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().

7a98306144 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).

3668a2e494 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.

8190ceb049 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.

a tty device instead of the legacy minor number approach.  This is known to

116d1ffddd 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.

"If the value of base is 16, the characters 0x or 0X may optionally

eae3ce693c 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.
