As of commit a449b889 ("x64: Enable sleeping in fault context") it's now
safe for another thread to enter a fault handler on the same CPU.  Fix
exception guard to reflect that.

This is needed for demand paging where a page fault from another thread
can happen on the same CPU where a thread is sleeping in the page fault
handler.

We have _KERNEL defines scattered throughout the code, which makes
understanding it difficult.

Define it just once, and adjust the source to build.

We define it in an overridable variable, so that non-kernel imported code
can undo it.

open()'s prototype is traditionally open(const char*, int, ...) since
the third mode_t parameter is optional, and only needed if O_CREAT is
specified.

Change the definition to conform.

This allows the LFS64() macro to be used to define open64() with a
similar prototype.

Signed-off-by: Avi Kivity <avi@cloudius-systems.com>

The vfs converts the read/write flags from 0/1/2 (read-only/write-only/rw) to
bit fields which are more easily testable.  But in doing so it corrupts the
other flags.

Fix FFLAGS and OFLAGS to preserve those other flags.  The test for a file
that is not readable or writable is dropped, since it is impossible to fail.
