81ed087074 - Rename struct linux_ctx to linux_fpctx. 
- KNF.

3bc2c4cf57 Now it uses BSD system calls with alternate path checks in compat/common, 
Darwin does not need freebsd_file.c anymore.

3b0f6d78ed Introduce BSD system calls with alternate patch checking (in /emul) in 
compat/common, so that they can be shared by several emulations, and use
them for Darwin.

This removes the ugly dependance on FreeBSD freebsd_file.c for COMPAT_DARWIN

e03fbf9432 The fp_status fasttrap is called processor_facilities_used in userland, and 
we discovered the flags it was to collect. Now we need to emulate them, but
it is another story.

load_msr seems only used from kernel code.

9b84721494 Added implementation for cthread_self() and cthread_set_self(). Theses are 
used to get and set the thread user value, which is an opaque pointer to
a per thread structure stored in userland. cthread_self() is used by Darwin
as an implementation for pthread_self(), which return the thread id.

We use the p_emuldata field of struct proc in order to keep track of the
thread user value. For now the value is per-process, but we will make it
per-thread when we will take care of threading.

While we are there, do some KNF

ef042d8e23 add a linux_rt_sigframe to support SA_SIGINFO, and use it when SA_SIGINFO 
is requested. This appears to be how linuxthreads decides which signal handler
to use.

e1e0ff678b move ELF-specific items from irix_exec.c to irix_exec_elf32.c 
merge the two emul_irix structures; the only difference was
  setregs function, which can be handled by exec-specific setregs hook
rename setregs_n32() to irix_n32_setregs(), and make it suitable
  as the exec-specific setregs hook
make irix_check_exec() a macro now that just single compare

c9710a72e0 Get the dynamic interpreter location using emul_find_interp(), so that 
it checks both the alternative/emul tree, and the non-emul tree.
This makes it possible to run chrooted emulated binaries without need
to setup shadow /emul tree within the chroot hierarchy.

XXX sligh code rearrangement was necessary, change not tested

Only tested for COMPAT_LINUX, changes to other compat modules were
mechanical.
