f703f1ef99 bulk: Do not declare function prototypes using 'extern' keyword 
By default, C function prototypes declared in headers are visible,
so there is no need to declare them as 'extern' functions.
Remove this redundancy in a single bulk commit; do not modify:

  - meson.build (used to check function availability at runtime)
  - pc-bios/
  - libdecnumber/
  - tests/
  - *.c

8a45962be3 bsd-user: Move PRAGMA_DISABLE_PACKED_WARNING etc to qemu.h 
For the moment, move PRAGMA_DISABLE_PACKED_WARNING and
PRAGMA_ENABLE_PACKED_WARNING back to bsd-user/qemu.h.

Of course, these should be in compiler.h, but that interferes with too
many things at the moment, so take one step back to unbreak clang
linux-user builds first. Use the exact same version that's in
linux-user/qemu.h since that's what should be in compiler.h.

a05cee93f4 linux-user: Use ARRAY_SIZE with bitmask_transtbl 
Rather than using a zero tuple to end the table, use a macro
to apply ARRAY_SIZE and pass that on to the convert functions.

This fixes two bugs in which the conversion functions required
that both the target and host masks be non-zero in order to
continue, rather than require both target and host masks be
zero in order to terminate.

This affected mmap_flags_tbl when the host does not support
all of the flags we wish to convert (e.g. MAP_UNINITIALIZED).
Mapping these flags to zero is good enough, and matches how
the kernel ignores bits that are unknown.

Fixes: 4b840f96 ("linux-user: Populate more bits in mmap_flags_tbl")

9c255cb53e bsd-user: Use page_check_range_empty for MAP_EXCL 
The previous check returned -1 when any page within
[start, start+len) is unmapped, not when all are unmapped.

63fd8ef080 target/i386: implement SYSCALL/SYSRET in 32-bit emulators 
AMD supports both 32-bit and 64-bit SYSCALL/SYSRET, but the TCG only
exposes it for 64-bit targets.  For system emulation just reuse the
helper; for user-mode emulation the ABI is the same as "int $80".

The BSDs does not support any fast system call mechanism in 32-bit
mode so add to bsd-user the same stub that FreeBSD has for 64-bit
compatibility mode.

7f750efcaa linux-user, bsd-user: Preserve incoming order of environment variables in the target 
Do not reverse the order of environment variables in the target environ
array relative to the incoming environ order.  Some testsuites depend on a
specific order, even though it is not defined by any standard.

2e2097b495 *-user: remove the guest_user_syscall tracepoints 
This is pure duplication now. Both bsd-user and linux-user have
builtin strace support and we can also track syscalls via the plugins
system.
