Introduced HAVE_CONFIG_H flag for each source file so config.h can be included safely. For now some things
collides with some edelib macros.
Added conditional code in emountd: if HAL is not present or system does not supports it, emountd will
be compiled without and will display a message about it.
Small modification in pkg.m4 so returned variables does not have ending spaces
s/DEBUG/DEBUG_PCRE in pcre.c so it does not gets included when ede is compiled with
debug flags
