Copy files from ../librthread in preparation for moving functionality

from libpthread to libc. No changes to the build yet, just making it easier to review the substantive diffs. ok beck@ kettenis@ tedu@

Wrap fpgetround() so internal calls to it (seen on arm, powerpc, and sh)

go direct instead of through the PLT. ok millert@ kettenis@

Stop using sigreturn for longjmp, just set the signal mask and return

registers ala _longjmp. In setjmp, stop saving the onstack from sigaltstack as it's been unused by longjmp for years. In sig{set,long}jmp, use the internal, hidden names for setjmp/_setjmp/etc to avoid creating PLT entries. build testing deraadt@

Wrap the remaining math functions in libc: fpclassify*(), flt_rounds(),

and ldexp(). ok millert@

Do provide hidden _libc_* aliases for sig{block,setmask} and use them in

the ASM *setjmp implementations. Skip the PLT when calling them on amd64 (other archs to do this after testing) ok miod@

Since the __{div,rem}{l,q}{,u} special libc entry points use a specific

calling convention which conflicts over t11 usage with the secureplt calling convention, force these symbols to be `notype' rather `function', so that the linker will not attempt to use plt relocations for them in the absence of explicit relocation information. Note that these symbols are still public and still callable with the old plt convention, so existing binaries will still work with an updated libc, and no libc version change is necessary.

Switch libc and libm to use strong aliases rather than weak aliases

where appropriate. Among other things makes the symbols consistent across all architectures (notably where ldbl mantissa is 53 bits). While at it, kill unused LINTLIBRARY/PROTOLIB1 cruft which was there to trick lint into recording the right prototypes for aliased functions. Most of the work done at the awesome n2k13 hackathon. Agreed by kettenis@, guenther@, matthew@.

Do not use , that is an deformed BSD-ism.

It turns out is the right file to pull in. ok millert

alloca.c cannot be used

2012-04-12T16:14:09Z

Revert (leaving the complex math part alone). Some stuff is depending

on this historical behavior; so we're stuck in this stupid situation. No cookie for me.
