version: 1.2.10 bugfix & LGPL v3 -> LGPL v2.1
bugfix: call zlog_clean_rest_thread in exit() mutilple times
bugfix: test/test_hashtable segment fault

In zc_hashtable.c, zc_hashtable_remove() and zc_hashtable_del() didn't check the
argument pass to it.  So, if pass NULL to them, they will dereference it, and if
we are lucky, it will segment fault.

This commit fix that problem.

zc_hashtable.c: add missing zc_error() argument in zc_hashtable_remove()

It still work because zc_error() will print something on stack if required
argument didn't given, but it does not do things we expected.
add stat logic to the static file rule

- this emulates Python's WatchedFileHandler for logging, where we check
  the inode of our logfile path to see if it was changed out from underneath
  us by an external tool like logrotate.

  This allows applications that use an external tool for log rotation/compression
  to have a simple log configuration and not have to worry about calling zlog_reload
  to reopen the new file after the external tool has run.
