Revert to binding *package* in bootstrappy code

I see no sane way to use sb!ext:print-symbol-with-prefix or
sb-ext:... in ~//. Bind *package* to :keyword instead, for
undefined function conditions.

Fix a typo in the block comment on encoding/decoding universal times

Might as well, while we're updating URLs.

s/32/n-word-bits/ in bignum-index

For some reason we missed that during all the work on x86-64. Then
again, our static inference is good enough that no runtime check
seem to be left to detect that the declaration is wrong.

Store FP values from x87 to the heap outside pseudo-atomic

It suffices to get the header right, and that way we avoid signaling
FPEs in PA, when, as is bound to happen, a value is only truncated
when it's boxed.

double->single float conversion isn't a no-op on x87 anymore

The conversion can result in overflow, so pass through a stack
temporary to force a truncation.

New contrib: SB-GMP

This contrib was developed by Stephan Frank to replace some of our
bignum and rational arithmetic code with calls to libgmp. Simply
loading the contrib will transparently accelerate arithmetic on
large rationals when libgmp is available; if libgmp cannot be found,
the contrib should change nothing.

The contrib also wraps additional functions in GNU MP, so that they
accept and return SBCL-native integers or ratios. See GNU MP's manual
for more information.

Defer some sanity checks to after testing for value refence to inline functions

The functional corresponding to an inline function can be marked as dead when
there remains references in for-value contexts. Detect such references before
making sure the function is still live.

Otherwise MAKE-THREAD could be interrupted after having
locked *MAKE-THREAD-LOCK*. If the interrupting code also called
MAKE-THREAD, a recursive lock attempt for *MAKE-THREAD-LOCK* would

The problem could be easily triggered by

(MAKE-TIMER ... :THREAD <T or a thread>)

Also move let bindings of SETUP-SEM, REAL-FUNCTION, ARGUMENTS and
INITIAL-FUNCTION and the NOT *GC-INHIBIT* assertion out of the
critical section.

Tests have been added in threads.pure.lisp and timer.impure.lisp.

Provide more info in debugger-disabled-hook.

Before this change if there was an error printing the condition object,
then we didn't even try printing the backtrace afterwards, which can be
a useful source of information even if the condition printing has failed.

Make the printing of a slot-unbound error more error tolerant.

Especially against errors coming from custom PRINT-OBJECT methods, in which
case only print the TYPE-OF the instance. Also, print fully qualified
symbol names.

Simplify EMIT-VOP further.

EMIT-VOP is only ever used in conjunction with INSERT-VOP-SEQUENCE, by
returning two values: first and last VOPs, all linked together,
INSERT-VOP-SEQUENCE then inserts them into the block. But nowadays
EMIT-VOP always returns the same VOP as the second value.
* EMIT-VOP now returns one value, the emitted VOP.
* INSERT-VOP-SEQUENCE is renamed to INSERT-VOP, accepts only one VOP.
* A new function EMIT-AND-INSERT-VOP is added, which combines them,
and is used anywhere where EMIT-VOP was used.

This makes things less complicated, and reduces core size by 32KB, the
same as the previous commit, for a total of 64KB of savings
essentially for free.

(Also squeeze a couple of line-break fixes)

Since there's only one kind of templates now, there's no need for
indirection. Rename EMIT-GENERIC-VOP to EMIT-VOP, remove EMIT-FUNCTION
slot from TEMPLATE, call EMIT-VOP directly.

backtrace: don't cons large lists when RCX is overwritten inside XEPs.

To present a list with the actual number of passed arguments in the
backtrace, clean-xep used the arg-count register and added missing
arguments in the form of #<unknown>, but if the register is
overwritten by other code, it could cons very large lists, exhausting
heap. Do such arg-list clean up only upon INVALID-ARG-COUNT-ERROR.
Fixes lp#1192929.

Hopefully fix the windows build to grovel time structures correctly.

It is a little misleading to say "correctly" since struct timespec
doesn't really exist on windows. Groveling the definition that we
define in our own pthreads wrapper seems the most consistent choice.

The grovel-headers.c changes have only been tested in isolation, not
with a real build. Thanks to Kyle Isom for testing, any resulting
build problems are entirely my fault.

Fix instruction encoding for XMM shifts with immediate count

x86 keeps getting more and more devious: the source/dest operand
is in the r/m field for these instructions, so REX.B must be set,
rather than REX.R, to access > xmm7. Intel's new documentation
seems clearer about these issues, at least.
