By default, C function prototypes declared in headers are visible,
so there is no need to declare them as 'extern' functions.

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

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.

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")

With reserved_va, mmap.c expects to have pre-allocated host address
space for the entire guest address space. When combined with the -B
command-line option, ensure that the chosen address does not overlap
anything else. Ensure that mmap_next_start is within reserved_va,
as we use it within mmap.c without checking.

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.
