This may help prevent ArrayIndexOutOfBounds randomly seen in CI. See ruby#125
* Parse base should be from current pointer so add that to the get calls. * Pull out ascii check into util method. * Rename curr local var to ptr to better match C version.
This is to align the base10 code with the freshly-ported base16 code. See ruby#125

Aha, so it does! I will tweak this to move the final integer parse and |
This aligns with C code that does the final parse and curr update in strscan_parse_integer.

Fix GH-152 CRuby can walk off the end because there's always a null byte. In JRuby, the byte array is often (usually?) the exact size of the string. So we need to check if len++ walked off the end. This code was ported from a version by @byroot in #127 but I missed adding this check due to a lack of tests. A test is included for both "-" and "+" parsing.

This is a re-port of the C code from @byroot for fast base 10 and base 16 integer scanning.
In #125, @kou pointed out there's an intermittent failure in the JRuby extension. We were unable to confirm exactly the circumstances that cause that failure, but this re-port should at least help reduce the change it is a bug in the original Java code.
