kleink 9e00e84f98 Restore the behaviour of not setting errno to ENOMEM when allocating 0
units of storage and returning a null pointer in System V mode; this was
broken by the `fix' in rev. 1.24.  Also, as it is stated in ISO C that
such operation does not constitute an allocation failure, do not abort()
even if the `X' option is set.

Amusingly enough the SVID, Fourth Edition, specifies the `unique pointer'
return behaviour for this kind of allocation, so this is kind of mis-named.

lukem c2601fffee replace malloc(3) with one from freebsd which documents our new malloc.c
(also from freebsd). comment out references to reallocf with .\"XXX"
for now. i also fixed some roff misuse as well.
replace calloc(3), free(3) and realloc(3) with links to malloc(3)

kleink 10ec438820 Add 3 additional slots to the statically allocated exit handler array to
guarantee the ANSI-defined 32 registrations being possible despite those exit
handler registrations made by the startup code (a.out: 2, ELF: 3).

simonb bf0aa4630d Changes from Niklas Hallqvist from OpenBSD. Commit message there was:
Make code ANSI/ISO C conformant.  Formerly undefined constructs were used
  making load/store architectures (like mips&alpha) fail whn compiled with
  gcc -O2.

Tested on mips and i386 ok.  Can someone with an alpha test this please?

kleink fd13be3c46 Protect access of state with a mutex. Miscellaneous notes:
* still needs an implementation-independent ("reentrant.h") method for
disabling cancellation,
* break a leg to leave realloc() `storage compaction' as was for non-reentrant
code,
* use of stdio in assertion code is unsafe.

kleink 5e62d8161d Exit via _exit() rather than exit(), as the latter would cause exit handlers
installed using atexit() to be executed which is supposed to happen on
`normal termination' of the process only, whereas abort() is specifically
defined to cause `abnormal termination'.

kleink c9f14e5e97 Addendum to previous commit: remove stdio usage from sections during which
random_mutex is locked, because
* a cancellation point may occur during fprintf(), and no cancellation handler
  had been installed, and
* the XSH5 specifcation of these functions does not permit output to stderr.
Therefore, in initstate() and setstate(), return a null pointer if the supplied
state is not valid.  This also fixes a bug in setstate() which caused corrupt
state information being used despite printing an error message.
