Corinna Vinschen ca2ec0c5cc Revert "Use allocation granularity as the 'page_size' in /proc/<pid>/status as well, for consistency with /proc/<pid>/statm"
This reverts commit 8a32c24a7b.

Replacing page_size() with allocation_granularity() was incorrect.
The values returned by get_mem_values() are # of pages of size
page_size().  Multiplying with allocation_granularity() here
results in values 16 times too big.

Corinna Vinschen 11dcf9cb5c Open process with PROCESS_QUERY_INFORMATION to fetch maps
Commit ba58e5f lowered permission requirements when opening threads
and processes to {PROCESS,THREAD}_QUERY_LIMITED_INFORMATION.  However,
when creating the /proc/<PID>/maps file, the call to VirtualQueryEx
requires PROCESS_QUERY_INFORMATION access

Note: It seems PROCESS_QUERY_LIMITED_INFORMATION is sufficient starting
with Windows 8.1, but this is neither documented on MSDN, nor is it a
safe bet.  It may have to do with a fixed implementation of the UAC
trust levels.  Let's better follow the docs for now.

Corinna Vinschen 532ecdd36f Add comment to point out missing access right per documentation
In get_mem_values we open the process without PROCESS_VM_READ access
and are *still* able to request working set information, despite
MSDN claiming we need it for this purpose.  Instead of adding this
access right, just add an comment to point this out for now.

Corinna Vinschen b2867a68b9 Handle up to 63 partitions per drive
Revamp device parsing code.  Introducing support for more partitions
into the shilka-generated parser has the unfortunate side-effect of
raising the size of the DLL by almost 2 Megs.  Therefore we split out
the handling for /dev/sdXY devices into a tiny bit of hand-written
code.

While at it, remove some unused cruft from devices.* and generally
clean up the device class to provide access methods instead of direct
access to members.

Peter Foley 0008bdea02 Refactor to avoid nonnull checks on "this" pointer.
G++ 6.0 asserts that the "this" pointer is non-null for member
functions.
Refactor methods that check if "this" is non-null to resolve this.

winsup/cygwin/ChangeLog:
external.cc (cygwin_internal): Check for a null pinfo before calling
cmdline.
fhandler_dsp.cc (Audio::blockSize): Make static.
fhandler_dsp.cc (Audio_in): add default_buf_info.
fhandler_dsp.cc (Audio_out): Ditto.
fhandler_dsp.cc (Audio_out::buf_info): Refactor method to call
default_buf_info if dev_ is null.
fhandler_dsp.cc (Audio_in::buf_info): Ditto.

	mountinfo or mounts output depending on the bool mountinfo argument.
	(format_process_mounts): Just call format_process_mountstuff with
	mountinfo set to false.
