05d405dade Add support for more open flags that have a native equivalent 
(O_NONBLOCK, O_DIRECT and O_NOFOLLOW).
Translate native EFTYPE error (missing on Linux) to expected ELOOP;
when opening symlinks with flag O_NOFOLLOW.

9cdb398e86 If SCARG(uap, what) = 0, copyin() will copy (size_t)-1 bytes, and it's not 
a good idea; but not proven harmful.

c1cf2f47fb A specially-crafted binary could easily control a kernel array index. 
Add some checks to ensure that nothing will be read outside the allocated
area. Rewrite the code so that we don't need to allocate the whole section.

Spotted by several developers, patch from chs@/enami@

b50661d98e CTASSERT that native to compat errno translation tables are kept in 
sync with native errno list.

Remove extra entries (linux) which resulted in bad translated values,
and add missing ones (ibcs2, osf1 and svr4) which made some out of
bounds accesses.
