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:

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 brk() to release pages
The current brk() implementation does not de-allocate pages if a lower
address is given compared to earlier brk() calls.
But according to the manpage, brk() shall deallocate memory in this case
and currently it breaks a real-world application, specifically building
the debian gcl package in qemu-user.
Fix this issue by reworking the qemu brk() implementation.
Tested with the C-code testcase included in qemu commit 4d1de87c750, and
by building debian package of gcl in a hppa-linux guest on a x86-64
host.

same way as print_raw_param(). This prevents that qemu_log() is used to
work around the problem that print_raw_param() can only print 32-bit

Additionally convert the existing 64-bit users in print_timespec64(),
print_rlimit64() and print_preadwrite64() over to this new function and
drop some unneccessary spaces.

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.

For sparc64, there does still exist trap 0x111 as tl0_oldlinux64,

-----------
linux-user/sparc: Handle coprocessor disabled trap
Since qemu does not implement a sparc coprocessor, all such
instructions raise this trap. Because of that, we never raise
the coprocessor exception trap, which would be vector 0x28.

linux-user/sparc: Handle unimplemented flush trap
For sparc64, TT_UNIMP_FLUSH == TT_ILL_INSN, so this is
already handled. For sparc32, the kernel uses SKIP_TRAP.

Raise SIGFPE for ieee exceptions.
The other types, such as FSR_FTT_UNIMPFPOP, should not appear,
because we enable normal emulation of missing insns at the
start of sparc_cpu_realizefn().

linux-user: fix bug about incorrect base addresss of gdt on i386 and x86_64
On linux user mode, CPUX86State::gdt::base from Different CPUX86State Objects
have same value, It is incorrect! Every CPUX86State::gdt::base Must points to
independent memory space.
