685e40bb09 syscall overhaul part two - unify public and internal syscall interface
with this patch, the syscallN() functions are no longer needed; a
variadic syscall() macro allows syscalls with anywhere from 0 to 6
arguments to be made with a single macro name. also, manually casting
each non-integer argument with (long) is no longer necessary; the
casts are hidden in the macros.

some source files which depended on being able to define the old macro
SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall()
instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL
have also been changed.

x86_64 has not been tested, and may need a follow-up commit to fix any
minor bugs/oversights.

d00ff2950e overhaul syscall interface
this commit shuffles around the location of syscall definitions so
that we can make a syscall() library function with both SYS_* and
__NR_* style syscall names available to user applications, provides
the syscall() library function, and optimizes the code that performs
the actual inline syscalls in the library itself.

previously on i386 when built as PIC (shared library), syscalls were
incurring bus lock (lock prefix) overhead at entry and exit, due to
the way the ebx register was being loaded (xchg instruction with a
memory operand). now the xchg takes place between two registers.

further cleanup to arch/$(ARCH)/syscall.h is planned.

f5ba2bc9ca various legacy and linux-specific stuff
this commit is part of an effort to make more of busybox work
out-of-the-box.

2b43ef8fc7 make sys/param.h not depend on PATH_MAX and NAME_MAX
this is a nonstandard header used only by backwards programs, but for
some reason it's extremely popular. the recent namespace cleanup fixes
broke it, because PATH_MAX and NAME_MAX will not be defined unless an
approriate feature test macro has been defined. moreover, it's too
late to just #define _GNU_SOURCE in param.h, since limits.h may have
already been included.

let's just hard-code standard values and be done with it.

e882756311 reorganize pthread data structures and move the definitions to alltypes.h
this allows sys/types.h to provide the pthread types, as required by
POSIX. this design also facilitates forcing ABI-compatible sizes in
the arch-specific alltypes.h, while eliminating the need for
developers changing the internals of the pthread types to poke around
with arch-specific headers they may not be able to test.
