* doxygen2man: Add option to read copyright line from the header file
This should help make builds reproducible.
I tried various methods of getting the date, using 'git' is no use as
it could be run from a tarball, using the file date doesn't work either
so this seems a reasonable compromise.
* man: Use SOURCE_EPOCH to make manpage dates reproducible
Also add build-aux/update-copyright.sh to keep header file
copyright lines up-to-date.
All code taken from knet
doxygen2man: Lots of fixes and features
a) Make it quieter in normal operation
b) add options for hard coded things (like company name)
c) handle typedef members of structures
d) tidy function pointers in structs
e) get header file name from the XML or commandline
d) Add support for @ref tags in description
e) add support for @note annotations
f) Don't print (null) if there is no @brief description
g) Add include prefix option
h) use strncat rather than strcat
* doxygen2man: Add utility to generate man pages from doxygen
This is in here from kronosnet so it cna be used by other parts
of the cluster stack.
