A whole bunch of minor cosmetic changes.
Alter the licensing of libstatgrab. The library part is now under the LGPL, whilst the tools/examples are under the GPL. Both licenses are included in the distribution (and are both now in CVS). Also made a minor alteration to the webpage where it said everything was licensed under the GPL.
Added strlcat/strlcpy (taken from openssh). Added a #define for both, and also atoll which we appear to of forgotten about when it was written. Removed that #ifdef around get_ll_match as atoll will now always be defined.
Initial support for NetBSD. This adds NetBSD support for everything except diskio stats (since they're even more disturbingly complex to get at on NetBSD than the three OSs we already support). Tested against NetBSD 1.6 on i386.
Add a helper function for opening the kvm handle. This removes a little bit of duplicated code, and means that we don't open and close kvm (which can potentially be quite expensive) each time we use it. This will also be useful for NetBSD.
Remove headers from tools.h that the prototypes don't need (since they're included elsewhere where needed). Include tools.h in tools.c, so we get warnings if the prototypes are wrong.
Tidy up of lots of little things. :)
Make the functions that use atoll have a #ifdef HAVE_ATOLL around them. I did this because freebsd doesn't have this function, and it doesn't need to run any of the functions in tools.h that uses them.
Removed getting of some data we didn't really need or use. Updated page_stats to work with linux. Fixed tools.h to compile nicely :)
Made network stats work with linux.
Useful tools, currently only one function. Function takes a file pointer and will read threw it until it hits a passed string. It will return that line.
