da1873aadd sys/targets: move targets from sys package 
This breaks circular dependency between:
sysgen -> sys/linux -> sys -> sysgen
With this circular dependency it is very difficult to
update format of generated descriptions because sysgen does not build.

66393d1884 pkg/compiler: don't genererate missing syscalls 
We used to generate them only because manager had no idea
what arch it is testing. So syscalls numbers had to match
between all arches.
This is not needed anymore.
Also don't generate unreferenced structs/resources.

539e603206 syz-manager, syz-fuzzer, executor: ensure that binaries are consistent 
Check that manager/fuzzer/executor are build on the same git revision,
use the same syscall descriptions and the same target arch.

487aa0d537 sys: consolidate info about various targets 
Info about targets (like C arch/CFLAGS) is required in multiple places:
extract.sh
syz-extract
syz-sysgen
csource
vm/qemu
...

Consolidate it in one place and use that in syz-sysgen.

ffe7e17368 prog, sys: move types to prog 
Large overhaul moves syscalls and arg types from sys to prog.
Sys package now depends on prog and contains only generated
descriptions of syscalls.
Introduce prog.Target type that encapsulates all targer properties,
like syscall list, ptr/page size, etc. Also moves OS-dependent pieces
like mmap call generation from prog to sys.

!t.BitfieldMiddle()
