(for real pwrite/pread. don't use the compatibility one - it works perfectly, but using it is pointless and may have unknown bugs, even though i know it's probably perfect) Signed-off-by: Leah Rowe <leah@libreboot.org>

7 dayslibreboot-utils: tidy up randLeah Rowe
make it more efficient. much lower rejection rate now, about 2-5%. deal with bias, but also get numbers in bulk. not too many. i'd say this is about right in terms of performance balance. 64 bytes == 8 large integers. Signed-off-by: Leah Rowe <leah@libreboot.org>

build-time option. do not allow fallback; on a system where getrandom is used, it should be used exclusively. on some systems, getrandom may not be available, even if they have a newer kernel. Signed-off-by: Leah Rowe <leah@libreboot.org>
