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.

Make newlib manpages via DocBook XML (v3)
Add makedocbook, a tool to process makedoc markup and output DocBook XML
refentries.
Process all the source files which are processed with makedoc with
makedocbook as well
Add chapter-texi2docbook, a tool to automatically generate DocBook XML
chapter files from the chapter .texi files. For generating man pages all we
care about is the content of the refentries, so all this needs to do is
convert the @include of the makedoc generated .def files to xi:include of
the makedocbook generated .xml files.
Add skeleton Docbook XML book files, lib[cm].in.xml which include these
generated chapters, which in turn include the generated files containing
refentries, which is processed with xsltproc to generate the lib[cm].xml
Add new make targets to generate and install man pages from lib[cm].xml

Fix major device check when locking partitions
The change introduced in commit b2867a6 contains a faulty check for

Fix this. Also fix comments.

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.

Use correct file info (especially inode number) for newly created files
fhandler_base::open_fs has two problems:
- When newly creating a file, the file info in the path_conv is
incorrect. It points to info for the parent dir, not to info
for the file itself (which, naturally, wasn't available before).
- Fetching the file's inode number only worked for non-NFS.
Both problems should be fixed now by reloading file info if the file
has just been created, as well as using the new FS-agnostic
path_conv::get_ino method.

Improve encapsulation of FS type behind path_conv cover
Rather than having to check for the FS type in the caller and having
to call different functions whether FS is NFS or not, encapsulate the
info in path_conv_handle/path_conv methods to allow FS type agnostic
calling from upper level functions.
Commit a23e6a35d896a075640db714b28ce74bb6b8d7ff introduced a timer
object to the WFMO handling in select_stuff::wait to allow sub-tickcount
timeout values in select.
Problems with this patch: The timer was created and destroyed on every
invocation of select_stuff::wait, thus potentially multiple times per
select. Also, since the timer was prepended to the WFMO hande list,
the timer handle could shadow actual events on other objects, given that
WFMO checks the objects in the order they have been specified in the
HANDLE array. The timer was also created/destroyed and added to the
HANDLE array even if it was not required.
This patch drops the local timer HANDLE and recycles the cw_timer HANDLE
in the cygtls area instead. Thus we typically don't need to create the
timer in select at all, and we never have to destroy it.
The timer HANDLE is now also appended as last object to the HANDLE array,
and it's only added if actually needed.
Fix condition in select which results in busy loop.
The check for current timestamp > start timestamp has an unwelcome
side effect: The loop is not left as long as the current timestamp
hasn't been incremented. This leads to busy loops of about one tick
(10 to 16 ms per MSDN).

Return at most one line of input in canonical mode
'man termios' says:
"A read(2) returns at most one line of input" in canonical mode.
On cygwin 2.5.1, read(2) returns all data in buffer if the buffer
size specified is large enough. This behaviour is correct in
noncanonical mode, but is not correct in canonical mode.
While checking this problem, I found a bug of tcflush(). tcflush()
flushes only partial data in the buffer. The patch also fixes this bug.
The patch has also been tested against the problem reported in
https://cygwin.com/ml/cygwin/2016-05/msg00318.html.
Only regenerate tlsoffsets{64}.h if cygtls.h can be compiled
The rule to make tlsoffset{64}.h has a flaw. If cygtls.h can't be
built for whatever reason, it *still* regenerates tlsoffsets{64}.h,
just with size 0. If the bug is not in cygtls.h itself, this behaviour
breaks further building, because fixing the problem won't result in
regenerating tlsoffset{64}.h. Manual intervention is required.
Fix that by removing tlsoffsets{64}.h if gentls_offsets fails.
Temporarily revert to use PROCESS_QUERY_INFORMATION instead of
PROCESS_QUERY_LIMITED_INFORMATION to make sure every aspect of the
next release is still XP/2003 compatible.
dlopen: Add dot to filename if no slash is present
We're appending a dot to the filename before calling LoadLibrary to

filenames since it required a slash in the pathname. Fix that.
