global: use i_rand_limit() and i_rand_minmax() when possible

global: Replace rand with i_rand

global: Require comparisons to be strict boolean expressions * No implicit integer -> boolean or pointer -> boolean conversions * !expr can be used only if expr is boolean type These were checked with a patched clang. It found various actual bugs, which were fixed by the previous commits.

Remove now-unnecessary direct stdlib.h #includes.

lib: Improved unit test for uni_utf8_get_char() return value check.

lib: test-unichar - test invalid utf8 encodings Chop trailing characters off valid encodings, and watch them fail. (There's no need to do this on most of the test characters, as they're truncated to the same byte sequence - only do 1 in 64.) Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: test-unichar - streamline the unichars test It's doing 2 kinds of tests, split them into separate test cases. And the first part has started to get expensive, so just make sure all code paths are tested by skipping most values. Only 3 from each set of 64 (lowest 6 bits) are tested.

lib: Fixed NUL-handling in uni_utf8_*strlen*() uni_utf8_strlen() could have skipped over the ending NUL byte and caused read buffer overflows with invalid input. uni_utf8_strlen_n() and uni_utf8_partial_strlen_n() now allow NUL bytes in the input and they're treated as regular control characters. Previously the size was actually treated as max_size with early NUL byte termination. Technically this is an API change, but I'm not aware of anything using these functions in an incompatible way.

lib: Added uni_utf8_partial_strlen_n()
