In particular this fixes some exceedingly rare/impossible use-after-frees. Add the new docs from the distribution and clarify where we get our code from. To maintain our alterations, the following patches have been applied to the source from upstream's repository (1221e987...75ea9ccb) to bring the source up to date: * 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.) * Fixed bug in 'lua_upvaluejoin' Bug-fix: joining an upvalue with itself could cause a use-after-free crash. * Fixed typos in comments * Fixed missing GC barriers in compiler and undump While building a new prototype, the GC needs barriers for every object (strings and nested prototypes) that is attached to the new prototype. * Updated release number and copyright year * Fixed bug: invalid mode can crash 'io.popen' * Fixed bug: Negation overflow in getlocal/setlocal * 'realloc' can fail when shrinking a block According to ISO C, 'realloc' can fail when shrinking a block. If that happens, 'l_alloc' simply ignores the fail and returns the original block. * Fixed bug of long strings in binary chunks When "undumping" a long string, the function 'LoadVector' can call the reader function, which can run the garbage collector, which can collect the string being read. So, the string must be anchored during the call to 'LoadVector'.
