Corinna Vinschen eb4bfe4621 cygwin: block devices: fix file offset after short writes 
When reading/writing block devices, Cygwin emulates Linux, providing
a byte-exact file position, albeit the underlying device drivers don't.

Unfortunately this only worked correctly for reading.  The raw_write
method failed to revalidate the buffer after the read-modify-write
cycle in case len is not a multiple of the sector length.  This in
turn resulted in lseek reporting a wrong file pointer.

Also, fix a condition for invalidating the buffer after writing from
a remaining read buffer.

Corinna Vinschen 67a657cb1d cygwin: mmap: fix a fork failure with private, anonymous mappings 
Rounddown incoming addr on a page boundary. Without this, we may end
up with a fork error for private, anonymous maps.  The reason is, we
use VirtualAlloc in this case which will potentially overcommit if
addr is not on a page boundary.  This isn't taken into account in
bookkeeping, but fixup_mmaps_after_fork will eventually stumble over
this when trying to reproduce the copy-on-write pages: VirtualQuery
returns a region reaching beyond the supposedly allocated address
range and from there it goes downhill.

Corinna Vinschen 0d57ef9de5 Cygwin: open: Remove unused code to handle HIDDEN and SYSTEM files 
Commit 603ef545bd broke this snippet and
commit 5b312b4747 didn't help at all since
FILE_CREATE is exactly *not* the situation the test was originally
supposed to handle.

In fact, none of the open flags used by fhandler_base::open actually
hits this problem anymore, so just drop the code.
