interface_set_client_capabilities() copies only the first few bits,
because it falls into a Classic C trap: you can declare a parameter
uint8_t caps[58], but the resulting parameter type is uint8_t *, not

Harmless, because the bits aren't used, yet. Broken in commit c10018d6. Spotted by Coverity.

about it. However, the actual comparison is off by one: <= end
instead of < end. Fix by rewriting the check in a cleaner way.

user: Consider symbolic links as possible directories
Commit 2296f194dfde4c0a54f249d3fdb8c8ca21dc611b reduced the number
of syscalls performed during user emulation startup, but failed to
consider the use of symbolic links in creating directory structures.
linux-user: Rewrite __get_user/__put_user with __builtin_choose_expr
The previous formuation with multiple assignments to __typeof(*hptr) falls
down when hptr is qualified const. E.g. with const struct S *p, p->f is
also qualified const.
With this formulation, there's no assignment to any local variable.
Use the new host endian unaligned access functions instead of
open coding byte-by-byte references. Remove assembly special
cases for i386 and ppc -- we've now exposed the operation to
the compiler sufficiently for these to be optimized automatically.
Move the bswap_N -> bswapN wrappers inside CONFIG_BYTESWAP_H.
Change the ultimate fallback defintions from macros to inline functions.
The proper types recieved by the function arguments means we can remove
unnecessary casts, making the code more readable.
Fixes the libfdt enabled build for hosts that have <machine/bswap.h>.
The code at the beginning of qemu/bswap.h is attempting to standardize
on bswapN. In the case of CONFIG_MACHINE_BSWAP_H, this is all we get.
In the case of CONFIG_BYTESWAP_H, we get bswap_N from the system header
and then wrap these with inline functions to get bswapN.
