lib: Add tests for str_is_float

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

Remove now-unnecessary direct stdlib.h #includes.

lib: test-strnum - do not invite undetectable errors The very numbers which could cause a broken parser to over-run, the ones we are testing, are the ones which will be parsed as having a value similar to 'value', so check that no value was returned by using a number completely dissimilar to that. Otherwise, there might be an accidental mis-parse that overwrote value, but left its value the same. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: strnum: Fixed test suite failure on 32 bit systems.

lib: Added some tests for the new strnum _hex() and _oct() function variants.

lib: test-strnum - fix format size mismatch Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: test-strnum - add size-oblivious str_to/parse_uintmax tests Test a value of every bit-length. Also test the 10/9*MAX corner case. And due to crappy helper functions, test lots of leading zeroes too! Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: remove uintmax tests from uint64 tests These log a warning on OSX with clang. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: test-strnum - tests for the new partial-string parser We can simplify the main tests by always testing whether an appended non-digit causes parsing to fail at the same time that we test it doesn't fail with the new more permissive helpers. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: test-lib - add unit tests for str_to_*() helpers This doesn't test all the helpers, but ensures both signed and unsigned are tested, as are 32-bit and 64-bit cases. All the other helpers fall back onto using one of those cases. Unless uintmax_t is larger than 64 bits, in which case this needs a revisit. NOTE: This causes the following make check errors: test-strnum.c:35: Assert(#7) failed: ret == u64tests[i].ret test-strnum.c:35: Assert(#10) failed: ret == u64tests[i].ret test-strnum.c:37: Assert(#10) failed: val == u64tests[i].val str_to_uint64 ........................................................ : FAILED Corresponding to test cases: [7] = INVALID(18446744073709551616), This does not wrap-past-0 (become smaller) on multiply, but wraps-past-0 on addition. [10]= INVALID(20496382304121724020), This wraps-past-n (becomes larger) on multiply. Signed-off-by: Phil Carmody <phil@dovecot.fi>
