cpphash.c (_cpp_destroy_hashtable): Use ht_destroy.
* cpphash.c (_cpp_destroy_hashtable): Use ht_destroy.
* cpphash.h (CPP_IN_SYSTEM_HEADER): Fix.
(struct cpp_pool): New member first.
* cppinit.c (append_include_chain): Plug memory leaks.
* cpplib.c (cpp_register_pragma, cpp_register_pragma_space):
Allocate pragma structures from the (aligned) macro pool to
avoid leaking memory.
* cpplex.c (_cpp_init_pool, _cpp_free_pool): Use pool->first
so we don't leak memory.
* hashtable.c (ht_destroy): New.
* hashtable.h (ht_destroy): New.
