0b19387dae headers: use configure.h as 1st. header 
Ensure configure.h is always 1st. included header.
Maybe we could eventually introduce gcc -include option, but for now
this better uses dependency tracking.

Also move _REENTRANT and _GNU_SOURCE into configure.h so it
doesn't need to be present in various source files.
This ensures consistent compilation of headers like stdio.h since
it may produce different declaration.

d5da55ed85 device_mapper: remove dbg_malloc. 
I wrote dbg_malloc before we had valgrind.  These days there's just
no need.

ccc35e2647 device-mapper: Fork libdm internally. 
The device-mapper directory now holds a copy of libdm source.  At
the moment this code is identical to libdm.  Over time code will
migrate out to appropriate places (see doc/refactoring.txt).

The libdm directory still exists, and contains the source for the
libdevmapper shared library, which we will continue to ship (though
not neccessarily update).

All code using libdm should now use the version in device-mapper.

7f97c7ea9a build: Don't generate symlinks in include/ dir 
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/

6521c4b215 libdaemon: Fix some client leaks. 
Free (and clear) h.protocol string on daemon_open() error paths
so it's OK for caller to skip calling daemon_close() if returned
h.socket_fd is -1.

Close h.socket_fd in daemon_close() to avoid possible leak.

1ce21c19d5 va_list: properly pass va_list through functions 
Code should not just pass va_list arg through the function
as args could be passed in many strange ways.
Use va_copy().

For details look in i.e.:

b7741f0a83 libdaemon: header cleanup 
Ensure  daemon-io.h is used as a generic header included
with configure defines before other headers.
(In future all lvm2 libraries should settle on a single lib.h header)
Rename couple defines to better match header file names.

bf29fa49d3 Use dm_strncpy instead of plain strncpy while setting the socket path. 
Also check the return value as it meaningless to work with truncated strings.
