Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.
Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.
First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.
Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

Fix reading of cpu_lock in gen_qemu_stql_c, original patch from Laurent
Desnogues.
A new flag was added to gen_store_mem to allocate local temps instead
of temps; this flag should be set when the tcg_gen_qemu_store callback
uses brcond before using the temps or else liveness analysis will get
rid of the temps.
This also adds lock printing in cpu_dump_state which can help
debug.

Hopefully pine doesn't corrupt this patch, I've had problems recently.
For an alpha "ret" instruction, of the type
ret $26
The return was being ignored. This is because in translate.c
register $26 (the return address) was being over-written with the current
PC before it could be jumped to. Thus the ret was ignored.
This patch just re-orders things so the return address is processed before
it is over-written with the current PC.

according to the alpha arch reference, the literal field of an operate
instruction is unsigned:
If bit <12> of the instruction is 1, an 8-bit zero-extended literal
constant is formed by bits
<20:13> of the instruction. The l teral is interpreted as a positive
integer bet ween 0 and 255
and is zero-extended to 64 bits.
This patch fixes the mis-interpretation of the literal field.

The CMOV instruction is defined by the alpha manual as:
CMOVxx Ra.rq,Rb.rq,Rc.wq !Operate format
CMOVxx Ra.rq,#b.ib,Rc.wq !Operate format
Operation:
IF TEST(Rav, Condition_based_on_Opcode) THEN
Rc ← Rbv
The current qemu behavior inverses Ra and Rb. This is fixed by this
patch.
