0818340e80 syz-manager: don't take mutex when serving static files 
Crash log serving does not touch any manager state.

aeaa0b58b9 travis: also install 32-bit libstdc++ 
The build is still broken with missing C++ headers.
Let's see if this helps.

62114d6064 Makefile: build target binaries into separate dirs 
We currently build binaries for all targets into bin.
This makes mess in bin/ and does not allow testing of different archs.
Build target binaries into bin/OS_ARCH/ subdirs.

Host binaries are still built into bin/.

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.

4f60e46e49 syz-manager: check that files we are using are not changing under us 
If kernel or syzkaller binaries are rebuilt when manager uses them,
nothing good will happen. Manager can start mixing coverage from
old and new kernels, or crash on unknown syscalls.

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.

52a33fd516 prog: remove default target and all global state 
Now each prog function accepts the desired target explicitly.
No global, implicit state involved.
This is much cleaner and allows cross-OS/arch testing, etc.

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.
