Import the #'clear-string API from GNU, use it in tls.c
src/ChangeLog addition:
2015-04-18 Aidan Kehoe <kehoea@parhasard.net>
* sequence.c (Fclear_string): New, API from GNU. Zero a string's
contents, making sure the text is not kept around even when the
string's data is reallocated because of a changed character
length.
* sequence.c (syms_of_sequence): Make it available to Lisp.
* lisp.h: Make it available to C code.
* tls.c (nss_pk11_password): Use it.
* tls.c (gnutls_pk11_password): Use it.
* tls.c (openssl_password): Use it.
tests/ChangeLog addition:
2015-04-18 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test #'clear-string, just added. Unfortunately there's no way to
be certain from Lisp that the old password data has been erased
after realloc; it may be worth adding a test to tests.c, but
*we'll be reading memory we shouldn't be*, so that gives me pause.
