2017-03-25	libvmon: wrap X-Macro parser state in a struct	Vito Caputo
	This makes no functional difference, but silences warnings about unused variables when -Wall is enabled.
2017-03-25	*: restore old indentation of switch cases	Vito Caputo
	In the course of applying the new style over the rest of the code I decided it's obnoxiouos and prefer the old way of indenting the cases one level from the switch. I know it wastes horizontal space and can see the value of flattening the cases with the switch, but once you start having variables at the start of the switch body, and blocked cases, it just starts becoming quite unattractive without the indentation.
2017-03-25	*: s/malloc/calloc/	Vito Caputo
	Eliminate some 0/NULL initializations.
2017-03-21	*: update copyrights for 2017	Vito Caputo

2017-03-21	libvmon: use pread() instead of lseek()+read()	Vito Caputo
	I had assumed pread wouldn't work on /proc files and that lseek to the start was the only safe form of seeking, but this seems to be working acceptably well even with buffer sizes of 2 requiring many sequential reads per sample. The lseek syscalls aren't free and it's nice to omit them entirely, and we're essentially being sequential in our pread() use, and always use a buffer that is large enough to fit everything in the first read anyways.
2017-03-21	libvmon: use local buffers for constructing paths	Vito Caputo
	The vmon->buf[_bis] buffers are nice to shrink to absurdly small sizes for testing changes, but we can't do that when they're reused for path construction. Just use local on-stack buffers for constructing paths, and now things continue to function just slower with vmon->buf[8].
2017-03-21	libvmon: shirt-circuit parse loop on final state	Vito Caputo
	This trivial change eliminates the final EOF realization read() syscall on every /proc file consumed for every process on every sample, which adds up.
2017-03-21	libvmon: style cleanups	Vito Caputo
	Bring libvmon code inline with the direction vwm has headed in terms of coding style. Entirely mechanical changes with one exception replacing a free()/=NULL idiom with try_free().
2017-03-14	libvmon: add "sys-wide" arg for sample callbacks	Vito Caputo
	We need to eventually plumb an vwm_overlays_t reference back to sample_cb, for now we'll just obviate the need for the vwm_ptr global by plumbing the vwm_t through.
2017-02-02	libvmon: use readdir() instead of readdir_r()	Vito Caputo
	readdir_r() has been deprecated in glibc
2016-09-09	libvmon: clear {children,threads}_changed when sampling	Vito Caputo
	The samplers may set these, but we need to clear them on every vmon_sample().
2016-09-09	build: Adopt GNU automake (and thus autotools)	Vito Caputo
	Trying this out now that there's a pile of files... sigh. Note this spuriously duplicates list.h @ src/libvmon/list.h, the old Makefile shared list.h between vwm and libvmon, but I'm letting them have their own instances with autotools. Libvmon was always an independent project I just pulled in for vwm's use, and will likely continue to be developed independent of vwm with occasional syncs.
2016-09-09	*: refactor all the things	Vito Caputo
	Long overdue house cleaning. The addition of compositing/monitoring overlays in vwm3 pushed vwm well past what is a reasonable size for a simple thousand line file. This is a first step towards restoring sanity in the code, but no behavioral differences are intended, this is mostly just shuffling around and organizing code. I expect some performance regressions initially, follow-on commits will make more improvements to that end as the dust settles.
