Implement epoll family system calls. This is a tiny wrapper around kqueue() to implement epoll subset of functionality. The kqueue user data are 32bit on i386 which is not enough for epoll user data, so we keep user data in the proc emuldata.
Initial patch developed by rdivacky@ in 2007, then extended by Yuri Victorovich @ r255672 and finished by me in collaboration with mjg@ and jillies@.

Implement most of timer_{create,settime,gettime,getoverrun,delete} for amd64/linux32. Fix the entirely bogus (untested) version from r161310 for i386/linux using the same shared code in compat/linux.
It is unclear to me if we could support more clock mappings but the current set allows me to successfully run commercial 32bit linux software under linuxolator on amd64.

Implement epoll support in Linuxulator. This is a tiny wrapper around kqueue to implement epoll subset of functionality. The kqueue user data are 32bit on i386 which is not enough for epoll user data so this patch overrides kqueue fileops to maintain enough space in struct file.

- >500 static DTrace probes for the linuxulator - DTrace scripts to check for errors, performance, ... they serve mostly as examples of what you can do with the static probe;s with moderate load the scripts may be overwhelmed, excessive lock-tracing may influence program behavior (see the last design decission)
Design decissions: - use "linuxulator" as the provider for the native bitsize; add the bitsize for the non-native emulation (e.g. "linuxuator32" on amd64) - Add probes only for locks which are acquired in one function and released in another function. Locks which are aquired and released in the same function should be easy to pair in the code, inter-function locking is more easy to verify in DTrace. - Probes for locks should be fired after locking and before releasing to prevent races (to provide data/function stability in DTrace, see the man-page of "dtrace -v ..." and the corresponding DTrace docs).

- Implement pipe2 syscall for Linuxulator. This syscall appeared in 2.6.27 but GNU libc used it without checking its kernel version, e. g., Fedora 10. - Move pipe(2) implementation for Linuxulator from MD files to MI file, sys/compat/linux/linux_file.c. There is no MD code for this syscall at all. - Correct an argument type for pipe() from l_ulong * to l_int *. Probably this was the source of MI/MD confusion.

Implement robust futexes. Most of the code is modelled after what Linux does. This is because robust futexes are mostly userspace thing which we cannot alter. Two syscalls maintain pointer to userspace list and when process exits a routine walks this list waking up processes sleeping on futexes from that list.

Add the linux 2.6.x stuff (not used by default!): - TLS - complete - pid/tid mangling - complete - thread area - complete - futexes - complete with issues - clone() extension - complete with some possible minor issues - mq*/timer*/clock* stuff - complete but untested and the mq* stuff is disabled when not build as part of the kernel with native FreeBSD mq* support (module support for this will come later)
Tested with: - linux-firefox - works, tested - linux-opera - works, tested - linux-realplay - doesnt work, issue with futexes - linux-skype - doesnt work, issue with futexes - linux-rt2-demo - works, tested - linux-acroread - doesnt work, unknown reason (coredump) and sometimes issue with futexes - various unix utilities in linux-base-gentoo3 and linux-base-fc4: everything tried worked
On amd64 not everything is supported like on i386, the catchup is planned for later when the remaining bugs in the new functions are fixed.
To test this new stuff, you have to run sysctl compat.linux.osrelease=2.6.16 to switch back use sysctl compat.linux.osrelease=2.4.2
Don't switch while running a linux program, strange things may or may not happen.

Add preliminary support for running 32-bit Linux binaries on amd64, enabled with the COMPAT_LINUX32 option. This is largely based on the i386 MD Linux emulations bits, but also builds on the 32-bit FreeBSD and generic IA-32 binary emulation work.
Some of this is still a little rough around the edges, and will need to be revisited before 32-bit and 64-bit Linux emulation support can coexist in the same kernel.
