6e8dcacd08 linux-user: Add code for PR_GET/SET_UNALIGN
This requires extra work for each target, but adds the
common syscall code, and the necessary flag in CPUState.

8f968b6a24 linux-user: Extract target errno to 'target_errno_defs.h'
We want to access the target errno indepently of the rest of the
linux-user code. Move the header containing the generic errno
definitions ('errno_defs.h') to 'generic/target_errno_defs.h',
create a new 'target_errno_defs.h' in each target which itself
includes 'generic/target_errno_defs.h'.

b1d2e476e9 linux-user: Remove obsolete F_SHLCK and F_EXLCK translation
These lock types are unsupported by Linux since v2.2[0][1] and
always return EINVAL (except on SPARC up until v2.6, which just
warned).

musl libc does not define these constants, so just remove them from
the translation cases.

fcb6fcf63b linux-user: Add generic 'termbits.h' for some archs
This patch introduces a generic 'termbits.h' file for following
archs: 'aarch64', 'arm', 'i386, 'm68k', 'microblaze', 'nios2',
'openrisc', 'riscv', 's390x', 'x86_64'.

Since all of these archs have the same termios flag values and
same ioctl_tty numbers, there is no need for a separate 'termbits.h'
file for each one of them. For that reason one generic 'termbits.h'
file was added for all of them and an '#include' directive was
added for this generic file in every arch 'termbits.h' file.

Also, some of the flag values that were missing were added in this
generic file so that it matches the generic 'termibts.h' and 'ioctls.h'
files from the kernel: 'asm-generic/termbits.h' and 'asm-generic/ioctls.h'.

1272a6c488 linux-user: Introduce TARGET_HAVE_ARCH_STRUCT_FLOCK
Bring target_flock definitions to be more in sync with the way
flock is defined in kernel.

Basically, the rules from the kernel are:

1. Majority of architectures have a common flock definition.

2. Architectures with 32-bit MIPS ABIs have a sligtly different
flock definition; those architectures are the only arcitectures
that have HAVE_ARCH_STRUCT_FLOCK defined, and that preprocessor
constant is used in the common header as a flag for including or
not including common flock definition.

3. Sparc architectures also have a sligtly different flock
definition, but the difference is only the padding at the end of
the structure. The presence of that padding is determined by
preprocessor constants __ARCH_FLOCK6_PAD and __ARCH_FLOCK64_PAD.

QEMU linux-user already implements rules 1. and 3. in a very
similar way as they are implemented in kernel. However, rule 2.
is implemented in a dissimilar way (for example, the constant
TARGET_HAVE_ARCH_STRUCT_FLOCK is missing), and this patch brings
QEMU implementation much closer to the kernel implementation.
TARGET_HAVE_ARCH_STRUCT_FLOCK64 constant is also introduced to
mimic HAVE_ARCH_STRUCT_FLOCK64 from kernel, but it is not defined
anywhere, however, this is the case with HAVE_ARCH_STRUCT_FLOCK64
in kernel as well.

bf9136722c linux-user: Fix target_flock structure for MIPS O64 ABI
Among MIPS ABIs, only MIPS O32 and N32 have special (different
than other architectures) definition of structure flock in kernel.

Bring target_flock definition in QEMU for MIPS O64 ABI to the
correct state, which is currently different than the most common
definition, and it should actually be the same.
