d16d704d62 PR port-i386/40143 Viewing an mpeg transport stream with mplayer causes crash 
Fix numerous problems:

1. LDT updates are not atomic.

2. Number of processes running with private LDTs and/or I/O bitmaps
   is not capped. System with high maxprocs can be paniced.

3. LDTR can be leaked over context switch.

4. GDT slot allocations can race, giving the same LDT slot to two procs.

5. Incomplete interrupt/trap frames can be stacked.

6. In some rare cases segment faults are not handled correctly.

a9a2ce837b Convert the syscalls.master to a format from which it is easier 
to parse and generate the compat name and basename (e.g. __stat50
and stat).  Use this to autogenerate __RENAME()'s to the rump_syscalls
header so that they can be called e.g. rump_sys_socket() instead
of rump_sys___socket30().

6709281d18 Move si_code definitions from MD to MI linux_siginfo.h, all archs

While here, remove unused/unneeded LINUX__SI_CODE macro. Only the
lower 16-bits are used for userland si_code.

92ce8c6a3d Make the emulations, exec formats, coredump, NFS, and the NFS server 
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime
