Minimal libc for sparc64. Reviewed by: obrien

# $FreeBSD$
Add an alternate signal trampoline to libc; add a wrapper for the sigtramp install sysarch, to be called from _start. This will allow the stack to be mapped non-executable, as required by the sparc v9 abi.

Handle alignment fault fixups in libc rather than in the kernel.

Emulate ldq and stq (load/store long double) instructions. GCC has started using these to load long doubles, but they aren't implemented in hardware on (at least) UltraSPARC I and II machines. Emulate popc in the user trap handler as well. Re-arrange slightly to make support functions more accessible. Reviewed by: tmm

- change ABI for user trap handler for sun4v (eventually will sync sparc64 no hardware set up to test at the moment) Approved by: scottl (standing in for mentor rwatson)

Connect user trap code to the build.

Install the userland signal trampoline when sigaction is first called, instead of on startup. This fixes binary compatibility of dynamically linked binaries from before the signal code move. Suggested by: wollman (a long time ago)

# Don't generate default code for these syscalls:
Generate the normal asm stubs for all sysv system calls. Use these instead of C wrappers for the *sys indirect system calls. The indirect system calls are horribly broken on sparc64. Submitted by: tmm

Add the mlockall() and munlockall() system calls. - All those diffs to syscalls.master for each architecture *are* necessary. This needed clarification; the stub code generation for mlockall() was disabled, which would prevent applications from linking to this API (suggested by mux) - Giant has been quoshed. It is no longer held by the code, as the required locking has been pushed down within vm_map.c. - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES to express their intention explicitly. - Inspected at the vmstat, top and vm pager sysctl stats level. Paging-in activity is occurring correctly, using a test harness. - The RES size for a process may appear to be greater than its SIZE. This is believed to be due to mappings of the same shared library page being wired twice. Further exploration is needed. - Believed to back out of allocations and locks correctly (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).
