[sr-dev] compilation warnings

i just compiled master, and got these warnings:

CC (cc) [M db_mysql.so] km_db_mysql.o km_db_mysql.c: In function ‘kam_mysql_mod_init’: km_db_mysql.c:93: warning: implicit declaration of function ‘db_mysql_alloc_buffer’

CC (cc) [M rls.so] resource_notify.o resource_notify.c:51:1: warning: "CONT_COPY" redefined In file included from rls.h:37, from resource_notify.c:38: ../presence/hash.h:52:1: warning: this is the location of the previous definition CC (cc) [M xcap_server.so] xcap_server.o xcap_server.c:422: warning: ‘xcaps_str_appsexml’ defined but not used

especially the first one sounds dangerous.
