lib: str_parse/to_*int*() - minor optimization

Updated copyright notices to include the year 2017.

lib: Add str_is_float check function

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/'

lib: strnum - simplify hex and oct overflow code uintmax_t is defined to have modulo-2^n semantics, and therefore the bottom bits of (uintmax_t) are guaranteed to be all set. Therefore the checking of the next character read is unnecessary, as it's already done in the loop control statement itself. (This is not true about the bottom digit base 10, which is why the check remains in the decimal case) Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: Added str_to_ino()

strnum: Implemented many more numeric string parsing functions. Created macros for most of the implementation to avoid further code duplication.

global: freshen copyright Robomatically: git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-4]/$1-2015/g;s/ (201[0-4]) Dovecot/ $1-2015 Dovecot/' Happy 2015 everyone! Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: strnum - ensure str_to_uintmax doesn't return a value on error It was clobbering the _r parameter even though the spec says it shouldn't. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: strnum - add permissive str_parse_uint() helper Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: strnum - add a permissive uoff_t parser Functions like these are so cookie-cutter, we may as well use a macro. Note that signed helpers, if they ever appear, will need more care. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: strnum - add permissive partial-string integer parser Not all strings we want to parse are already strtok'ed into separate pieces. Therefore add helpers which will read the integer, and return a pointer past the parsed integer. The previous helpers can be considered a special case which just follows up with a check that the '\0' has been reached. Showing a preference for const pointers generally, this does not try to mimic the non-const interface of strto{l,ul,ll,ull}(). Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: strnum - harden str_to_uintmax against overflows The invalid number "20496382304121724020" (2^64*10/9) will be parsed as valid. 2049638230412172402 * 10 does not noticably wrap, it becomes 2049638230412172404 Do not perform operations which might wrap, and then try to detect the issue, just compare with the known fixed bounds before doing the multiplication.

Updated copyright notices to include year 2014.

Replaced all -1U and (unsigned int)-1 with UINT_MAX. It's somewhat clearer this way. Also clang's -fsanitize=integer gives runtime errors about -1U (but not about explicit casts, so no need to change (type)-1 casts).

Oops :) Update copyrights to 2013 without breaking all .c files.
