Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()

The setjmp() function doesn't specify whether signal masks are saved and
restored; on Linux they are not, but on BSD (including MacOSX) they are.
We want to have consistent behaviour across platforms, so we should...

coroutine: move pooling to common code

The coroutine pool code is duplicated between the ucontext and
sigaltstack backends, and absent from the win32 backend. But the
code can be shared easily by moving it to qemu-coroutine.c.

configure: Split valgrind test into pragma test and valgrind.h test

Split the configure test that checks for valgrind into two, one
part checking whether we have the gcc pragma to disable unused-but-set
variables, and the other part checking for the existence of valgrind.h....

coroutine-ucontext: Help valgrind understand coroutines

valgrind tends to get confused and report false positives when you
switch stacks and don't tell it about it.

coroutine: switch per-thread free pool to a global pool

ucontext-based coroutines use a free pool to reduce allocations and
deallocations of coroutine objects. The pool is per-thread, presumably
to improve locality. However, as coroutines are usually allocated in...

coroutine: introduce coroutines

Asynchronous code is becoming very complex. At the same time
synchronous code is growing because it is convenient to write.
Sometimes duplicate code paths are even added, one synchronous and the
other asynchronous. This patch introduces coroutines which allow code...
