Kees Cook c430f60036 fortify: Move remaining fortify helpers into fortify-string.h 
When commit a28a6e860c ("string.h: move fortified functions definitions
in a dedicated header.") moved the fortify-specific code, some helpers
were left behind. Move the remaining fortify-specific helpers into
fortify-string.h so they're together where they're used. This requires
that any FORTIFY helper function prototypes be conditionally built to
avoid "no prototype" warnings. Additionally removes unused helpers.

Francis Laniel a28a6e860c string.h: move fortified functions definitions in a dedicated header. 
This patch adds fortify-string.h to contain fortified functions
definitions.  Thus, the code is more separated and compile time is
approximately 1% faster for people who do not set CONFIG_FORTIFY_SOURCE.
