unlike the previous definition, NSIG/_NSIG is supposed to be one more than the highest signal number. adding this will allow simplifying libc-internal code that makes signal-related syscalls, which can be done as a later step. some apps might use it too; while this usage is questionable, it's at least not insane.

also handle the non-GNUC case where alignment attribute is not available by simply omitting it. this will not cause problems except for inclusion of mcontex_t/ucontext_t in application-defined structures, since the natural alignment of the uc_mcontext member relative to the start of ucontext_t is already correct. and shame on whoever designed this for making it impossible to satisfy the ABI requirements without GNUC extensions.

sigsetjmp: store temporaries in jmp_buf rather than on stack.

it's essential to decrement the stack pointer before writing to new stack space, rather than afterwards. otherwise there is a race condition during which asynchronous code (signals) could clobber the data being stored. it may be possible to optimize the code further using stwu, but I wanted to avoid making any changes to the actual stack layout in this commit. further improvements can be made separately if desired.

apparently some other archs have sys/io.h and should not break just because they don't have the x86 port io functions. provide a blank bits/io.h everywhere for now.
-

based on proposal by Isaac Dunham. nonexistance of bits/io.h will cause inclusion of sys/io.h to produce an error on archs that are not supposed to have it. this is probably the desired behavior, but the error message may be a bit unusual.

based on code sent to the mailing list by nsz, with minor changes.

put some macros that do not differ between architectures in the main header and remove from bits. restructure mips header so it has the same structure as the others.

raise overflow and underflow when necessary, fix various comments.

similar to exp.c cleanup: use scalbnf, don't return excess precision, drop some optimizatoins. exp.c was changed to be more consistent with expf.c code.

fortunately the memory corruption could not hurt anything, but it prevented clearing the final newline and thus prevented the last path element from working.

this is mostly junk, but a few programs with tape-drive support unconditionally include it, and it might be useful.

priority inheritance is not yet supported, and priority protection probably will not be supported ever unless there's serious demand for it (it's a fairly heavy-weight feature). per-thread cpu clocks would be nice to have, but to my knowledge linux is still not capable of supporting them. glibc fakes them by using the _process_ cpu-time clock and subtracting the thread creation time, which gives seriously incorrect semantics (worse than not supporting the feature at all), so until there's a way to do it right, it will remain as a stub that always fails.

* old code relied on sign extension on right shift * exp2l ld64 wrapper was wrong * use scalbn instead of bithacks

this allows using the dynamic linker as a command to load programs.

overflow and underflow was incorrect when the result was not stored. an optimization for the 0.5*ln2 < |x| < 1.5*ln2 domain was removed. did various cleanups around static constants and made the comments consistent with the code.

incomplete but at least partly working. requires all files to be compiled in the new "secure" plt model, not the old one that put plt code in the data segment. TLS is untested but may work. invoking the dynamic linker explicitly to load a program does not yet handle argv correctly.

although a number is reserved for it, this option is not implemented on Linux and does not work. defining it causes some applications to use it, and subsequently break due to its failure.

previous version did not compare at all; it was just a fancy atomic write. untested. further atomic fixes may be needed.
