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.

2023-08-09linux-user: Use ARRAY_SIZE with bitmask_transtblRichard Henderson
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.
