Replace old and not so informal srand()/rand() calls to new random
number API.
Including btrfs-corrupt-block(main user), btrfs-image and btrfs-crc.
Some tests like dir-test/random-test/quick-test is not modified.
As random-test itself can't even pass build.

Since this patch:
btrfs-progs: move the check_argc_* functions into utils.c
All tools including the independent tools(e.g. btrfs-image, btrfs-convert)
can share the convenience of the check_argc_* functions, so this patch
adopt the argc check functions globally.

(same as commit bb0eabc383)
There, 'char' is unsigned, so once assigned '-1' from getopt, it gets
the value 255. Then, it compared to '-1' gives false.

This tool can be used to compute btrfs' style crc32c checksums for filenames
as done by the kernel. Additionally, there is -c mode to do a brute force
search for file names with a given checksum.
