A few bits and pieces to support the vhd daemon
* Introduce a dereferencing type to camldm so that PVs can be referenced by ID rather than by device name. This is useful for passing a device-mapper table between hosts where the physical device for a particular PV is different.
* Implement device-mapper reload/suspend/resume so that a table can be changed without tearing down the device
* A few more helper functions for stdext

CA-36075: add back in a sane default $PATH for subprocesses that need it.
In particular the 'EXTSR' storage backend expects to find 'pvcreate' on the path. Rather than just fixing this one instance and then seeing what else fails, this patch should prevent this class of error recurring.
Note that the only place we actually pass a custom environment to a subprocess is when installing the debian etch template.

Use autoconf to detect: xen headers; XS_RESTRICT in patchqueue; ocaml packages xmlm, type-conf; libdevicemapper; and linux-specific CDROM ioctls.
Modify the xen-api-libs.hg master Makefile to conditionally compile only those libraries whose system dependencies are met. So we:
* don't compile the xen libraries (xc, xb etc) if xen/xen.h is missing
* don't compile the cdrom library if the linux ioctls are missing
* don't compile the xml-light2, rss libraries if xmlm is missing
* don't compile rpc-light if type-conv is missing
* don't compile camldm if libdevicemapper is missing
This makes it easier for these libs to be used by other tools which may not need (eg) the xen or devicemapper bindings. Note that xen-api.hg needs most of these so any missing library will lead to a xen-api.hg build failure.

Switch all xapi syslog logging to 'local6' rather than 'daemon' (ie same as blktapcntrl is about to use). This allows us to (i) keep logging through syslog; but (ii) define in the syslog.conf whether the data is written synchronously or not.

Typing 'make doc' will generate documentation for the libraries in xen-api-libs. The documentation is integrated in the xen-api documentation (the custom ocamldoc generator in xen-api.hg is used). This only works when xen-api.hg is present in myrepos and 'make doc' has been executed in it.

CA-28788: fix the 'atomic_write_to_file' function which always ended up setting the perms to 0o0 despite the face that it tries to set them to 0o644.
As AndyP points out, the 'temp_file_in_dir' function creates the file with 0o0 and Unix.open only uses the given permissions if it actually creates a file. Therefore we add a Unix.chmod to set the permissions we want.
