Valgrind uses magic code sequences to define an ABI that the client may use to request behavior from the host. In particular, this may be used to inform valgrind about custom allocators, such as the one used in U-Boot.
This adds headers defining these sequences to U-Boot. It also adds a config option to disable emission of these sequences entirely, in the (likely) event that the user does not wish to use valgrind. Note that this option is called NVALGRIND upstream, but was renamed (and inverted) to CONFIG_VALGRIND. Aside from this and the conversion of a few instances of VALGRIND_DO_CLIENT_REQUEST_EXPR to STMT, these headers are unmodified.
These headers were copied from valgrind 3.16.1-4 as distributed in Arch Linux. They are licensed with the bzip2 1.16 license. This appears to be a BSD license with some clauses from Zlib.

Applied to u-boot/master, thanks!
