These functions aren't meant to be used directly by the test programs,
reflect that by making the declarations a little harder to reach, but
still available enough if there's a need to override them.

Original rationale behind using write in testutil was to accommodate
no-stdio builds. But is there evidence that no-stdio users would have
write or pre-defined meaning for file descriptors 1 and 2? Correct
answer is to provide way for no-stdio users who want to exercise
tests to plug in own BIO, not to make assumption that they have write.
And since we don't have to make such assumption, we can as well go
for simplest that works with standard library as specified by C
language standard.

'j' is specified as modifier for "greatest-width integer type", which in
practice means 64 bits on both 32- and 64-bit platforms. Since we rely
on __attribute__((__format__(__printf__,...))) to sanitize BIO_print
format, we can use it to denote [u]int64_t-s in platform-neutral manner.

Clang was complaining about some variables possibly being uninitialized
when used. The warnings are bogus, but clang can't figure that out. This
silences the warnings.
