165389b27b New interface to function 'luaL_openselectedlibs' 
Instead of preloading all non-loaded libraries, there is another
mask to select which libraries to preload.

0c9bec0d38 Better handling of size limit when resizing a table 
Avoid silent conversions from int to unsigned int when calling
'luaH_resize'; avoid silent conversions from lua_Integer to int in
'table.create'; MAXASIZE corrected for the new implementation of arrays;
'luaH_resize' checks explicitly whether new size respects MAXASIZE.
(Even constructors were bypassing that check.)

3e9dbe143d New function 'table.create' 
Creates a table preallocating memory. (It just exports to Lua the API
function 'lua_createtable'.)

17e0c29d9b Clear interface between references and predefines 
The reference system has a defined way to add initial values to the
table where it operates.

e288c5a918 Bug: Yielding in a hook stops in the wrong instruction 
Yielding in a hook must decrease the program counter, because it already
counted an instruction that, in the end, was not executed. However,
that decrement should be done only when about to restart the thread.
Otherwise, inspecting the thread with the debug library shows it one
instruction behind of where it really is.

12b6f610b0 Several tweaks in the garbage collector 
- back with step size in collectgarbage("step")
- adjustments in defaults for some GC parameters
- adjustments in 'luaO_codeparam'

e81f586001 Removed compatibility option LUA_COMPAT_GCPARAMS 
The meaning of different GC parameters changed, so there is point in
supporting old values for them. The new code simply ignores the
parameters when changing the GC mode, so the incompatibility is small.

e2cc179454 New option "setparms" for 'collectgarbage' 
The generational mode also uses the parameters for the incremental
mode in its major collections, so it should be easy to change those
parameters without having to change the GC mode.

6d042a178f Auxiliary buffer uses external strings

7923dbbf72 Bug: Recursion in 'getobjname' can stack overflow 
'getobjname' now broken in two, a basic version that handles locals,
upvalues, and constants, and a full version, which uses the basic
version to handle table accesses (globals and fields).

6baee9ef9d Removed test for "corrupted binary dump"

different number types.)

14e416355f Added suport for Fixed Buffers 
A fixed buffer keeps a binary chunk "forever", so that the program
does not need to copy some of its parts when loading it.

09f3c2372f Option '-l' discards version sufix from file name 
Like 'require', the command-line option '-l' discards an optional
version suffix (everything after an hyphen) from a file name when
creating the module name.

ab859fe59b Bug: Loading a corrupted binary file can segfault 
The size of the list of upvalue names are stored separated from the
size of the list of upvalues, but they share the same array.

314745ed84 Avoid excessive name pollution in test files 
Test files are more polite regarding the use of globals when locals
would do, and when globals are necessary deleting them after use.

997f11f543 Bug: 'break' may not properly close variable in a 'for' loop 
Function 'leaveblock' was generating "break" label before removing
variables from the closing block. If 'createlabel' created a 'close'
instruction (which it did when matching a goto/break that exited
the scope of an upvalue), that instruction would use the wrong level.
