The suppression engine was not creating the shared pointer to
regex_t in the proper way that would correctly free the memory
allocated by the glibc's regcomp function.
This patch fixes that.
* include/abg-sptr-utils.h (build_sptr<T>): Declare an overload that
allocates a T* and wraps it into a shared_ptr<T>.
(build_sptr<regex_t>): Declare a specialization for regex_t.
* src/abg-corpus.cc (build_sptr<regex_t>()): Define the
specialization here.
* src/abg-suppression.ccp
(suppression_base::priv::{get_file_[not]_name_regex,
get_soname_[not]_regex}): Use the new build_sptr<regex_t>().
(type_suppression::priv::{get_type_name_regex,
get_source_location_to_keep_regex}): Likewise.
(function_suppression::parameter_spec::priv::get_type_name_regex):
Likewise.
(function_suppression::priv::{get_name_regex,
get_return_type_regex, get_symbol_name_regex,
get_symbol_version_regex}): Likewise.
(variable_suppression::priv::{get_name_regex,
get_symbol_name_regex, get_symbol_version_regex,
get_type_name_regex}): Likewise.
