libfdt: Increase namespace-pollution paranoia
libfdt is supposed to easy to embed in projects all and sundry. Often, it won't be practical to separate the embedded libfdt's namespace from that of the surrounding project. Which means there can be namespace conflicts between even libfdt's internal/static functions and functions or macros coming from the surrounding project's headers via libfdt_env.h. This patch, therefore, renames a bunch of libfdt internal functions and macros and makes a few other chances to reduce the chances of namespace collisions with embedding projects. Specifically: - Internal functions (even static ones) are now named _fdt_*() - The type and (static) global for the error table in fdt_strerror() gain an fdt_ prefix - The unused macro PALIGN is removed - The memeq and streq macros are removed and open-coded in the users (they were only used once each) - Other macros gain an FDT_ prefix - To save some of the bulk from the previous change, an FDT_TAGALIGN() macro is introduced, where FDT_TAGALIGN(x) == FDT_ALIGN(x, FDT_TAGSIZE) Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
