Disable config from file or envvar with build flag

Browse source 
This adds a new autoconf flag, --disable-user-config, which disables
reading the configuration from /etc/malloc.conf or the MALLOC_CONF
environment variable. This can be useful when integrating jemalloc in a
binary that internally handles all aspects of the configuration and
shouldn't be impacted by ambient change in the environment.
