linux-user: Emulate CLONE_PIDFD flag in clone()
Add emulation for the CLONE_PIDFD flag of the clone() syscall.
This flag was added in Linux kernel 5.2.
Successfully tested on a x86-64 Linux host with hppa-linux target.
Can be verified by running the testsuite of the qcoro debian package,
which breaks hard and kills the currently logged-in user without this
patch.

linux-user: Add translation for argument of msync()
msync() uses the flags MS_ASYNC, MS_INVALIDATE and MS_SYNC, which differ
between platforms, specifcally on alpha and hppa.
Add a target to host translation for those and wire up a nicer strace
output.
This fixes the testsuite of the macaulay2 debian package with a hppa-linux
guest on a x86-64 host.

linux-user: handle netlink flag NLA_F_NESTED
Newer kernel versions require this flag to be present contrary to older
ones. Depending on the libnl version it is added or not.
Typically when using rtnl_link_inet6_set_addr_gen_mode, the netlink
packet generated may contain the following attribute:
with libnl 3.4
{nla_len=16, nla_type=IFLA_AF_SPEC},
[
{nla_len=12, nla_type=AF_INET6},
[{nla_len=5, nla_type=IFLA_INET6_ADDR_GEN_MODE}, IN6_ADDR_GEN_MODE_NONE]
]
with libnl 3.7
{nla_len=16, nla_type=NLA_F_NESTED|IFLA_AF_SPEC},
[
{nla_len=12, nla_type=NLA_F_NESTED|AF_INET6},
[{nla_len=5, nla_type=IFLA_INET6_ADDR_GEN_MODE}, IN6_ADDR_GEN_MODE_NONE]]
]
Masking the type is likely needed in other places. Only the above cases
are implemented in this patch.

linux-user: Fix unaligned memory access in prlimit64 syscall
target_rlimit64 contains uint64_t fields, so it's 8-byte aligned on
some hosts, while some guests may align their respective type on a
4-byte boundary. This may lead to an unaligned access, which is an UB.
Fix by defining the fields as abi_ullong. This makes the host alignment
match that of the guest, and lets the compiler know that it should emit
code that can deal with the guest alignment.
While at it, also use __get_user() and __put_user() instead of
tswap64().

linux-user: Fix access to /proc/self/exe
When accsssing /proc/self/exe from a userspace program, linux-user tries
to resolve the name via realpath(), which may fail if the process
changed the working directory in the meantime.
An example:
- a userspace program ist started with ./testprogram
- the program runs chdir("/tmp")
- then the program calls readlink("/proc/self/exe")
- linux-user tries to run realpath("./testprogram") which fails
because ./testprogram isn't in /tmp
- readlink() will return -ENOENT back to the program
Avoid this issue by resolving the full path name of the started process
at startup of linux-user and store it in real_exec_path[]. This then
simplifies the emulation of readlink() and readlinkat() as well, because
they can simply copy the path string to userspace.
I noticed this bug because the testsuite of the debian package "pandoc"
failed on linux-user while it succeeded on real hardware. The full log
is here:

block/fuse: Let PUNCH_HOLE write zeroes
fallocate(2) says about PUNCH_HOLE: "After a successful call, subsequent
reads from this range will return zeros." As it is, PUNCH_HOLE is
implemented as a call to blk_pdiscard(), which does not guarantee this.
We must call blk_pwrite_zeroes() instead. The difference to ZERO_RANGE
is that we pass the `BDRV_REQ_MAY_UNMAP | BDRV_REQ_NO_FALLBACK` flags to
the call -- the storage is supposed to be unmapped, and a slow fallback
by actually writing zeroes as data is not allowed.
