Modified Files:
        src/lib/libc/stdio: fread.c

Log Message:
for unbuffered I/O arrange for the destination buffer to be filled in one
go, instead of triggering long series of 1 byte read(2)s; this speeds up
fread() several order of magnitudes for this case, directly proportional
to the size of the supplied buffer

change adapted from OpenBSD rev. 1.19

fixes PR lib/55808 by Roland Illig
