Roberto Ierusalimschy 1221e987fe Bug: Long brackets with a huge number of '=' causes overflow 
A long bracket with too many equal signs can overflow the 'int' used for
the counting and some arithmetic done on the value. Changing the counter
to 'size_t' avoids that. (Because what is counted goes to a buffer, an
overflow in the counter will first raise a buffer-overflow error.)

Roberto Ierusalimschy 063d4e4543 Lua 5.3.5 ported to git 
This is the first commit for the branch Lua 5.3. All source files
were copied from the official distribution of 5.3.5 in the Lua site.
The test files are the same of 5.3.4. The manual came from the
previous RCS repository, revision 1.167.1.2.

Roberto Ierusalimschy 0232fbffbe now that 'luaO_str2num' always accepts a dot as a radix character, 
the lexer does not need to bother with this issue.
