cleaner and more correct code for 'luaD_shrinkstack' (the old test "inuse <= LUAI_MAXSTACK" for stack overflow is not correct, as the real maximum usable size is "LUAI_MAXSTACK - EXTRA_STACK")

bug (with compat on): 'ipairs' can work with any type that provides an __index; so, 'pairsmeta' should not check for tables. ('pairs' already checks for tables through 'next'.)

do not eliminate varargs from functions that do not use varargs (confuses the debug lib and gains very little in performance)

bug: When a coroutine tries to resume a non-suspended coroutine, it coud do some mess (and break C assertions) before detecting the error. Now it tests for those errors before anything else.

Handling of LUA_PATH/LUA_CPATH moved from package library to stand alone interpreter (so that 'lua.c' concentrates all handling of environment variables)

'string.format("%q")' writes 'math.mininteger' in hexa, to ensure it is read back as an integer

do not convert decimal constants with overflow to integers. (Therefore, they will be converted as floats)

'io.read("n")' accepts both a dot and the locale point as its radix character + 'MAXRN' -> 'L_MAXLENNUM' + small detail in 'test2'

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

do not try to ensure that 'sweepgc' points to a live object when entering sweep phase ('entersweep'); that may be too expensive to be done still inside the atomic step. Walking one single object more often than not will work.

call 'checkGC' *after* creating new objects (this is how 'execute' does it) (It increases the changes that 'allgc' start with a non-white object, which helps 'entersweep')

no more extra space in 'luaL_checkstack'. (It was already useless for the first call, and function works ok without that space anyway (just error message misses the 'msg' component)

'luaV_fastget' only treats the real fast case (table with a non-nil value at given key, so that it does not need to check metamethods)
