Features

• Remove autogenerated files from git repo (configure, Makefile.in, conftools, rrd_config.h.in)

• Reads $RRD_LOCKING environment variable and adds --locking option to some tools. The updatex api has been also
  updated to support setting locking related bits in its extra_flags parameter. @ensc

  This allows now to choose between three kinds of locking:

  none: no locking is done at all; caller has to do it manually and can implement e.g., a timeout with alarm(2) or so
  try: fails when lock is hold by another process; users will see "ERROR: could not lock RRD". This is the default and the only possible mode with the old code
  block: waits until lock is available.

  It can be used like
  env RRD_LOCKING=block rrdupdate ...
  or
  rrdupdate --locking none ...
  or
  rrd_updatex_r(filename, tmplt, RRD_FLAGS_LOCKING_MODE_BLOCK, ...);

• Add (remote) dump support to rrdcached @thz

• Constify argv argument to library functions
  Without this, users of library function that want to pass in const strings need to duplicate them to avoid compiler warnings

• Avoid multiple implementations of asprintf
  The locale-independent rrd_asprintf is equivalent to platform-provided snprintf when strings and integers are formatted.
  There is no user of vasprintf-msvc that is locale-dependent, therefore this implementation can be replaced with rrd_vasprintf.
