* examples/sfrom.c (main): Avoid unnecessary memory allocation.
* libmailutils/mailbox/mailbox.c: Likewise.

* frm/frm.h: Include mailutils/alloc.h, remove xalloc.h
* mh/mh.h: Likewise.

* include/mailutils/locker.h (mu_locker_set_default_external_program):
Change returned type.
* include/mailutils/mailbox.h (mu_set_folder_directory): Change
returned type.
* libmailutils/base/locker.c (mu_locker_set_default_external_program):
Return int (error code).
* libmailutils/base/tilde.c: Add extra checks
* libmailutils/mime/mimehdr.c (_mime_header_parse): Bugfix.
* mail/folders.c: Don't use alloca, use mu_alloc instead. It
was the only use of that function in Mailutils, so this change
allows to withdraw the alloca module.

* gnulib.modules (alloca, malloc)
(realloc, xalloc): Remove.
