f407b3c4a1 Using CIST_CLSRET instead of trick with 'nresults' 
The callstatus flag CIST_CLSRET is used in all tests for the
presence of variables to be closed in C functions.

93fd6892f8 Fixed bug in 'multiline' 
'incomplete' was popping error message that should be used in case
there is no more lines to complete the input, that is, 'pushline'
returns NULL, due to end of file.

366c855648 lua.c loads 'readline' dynamically 
(See comments in luaconf.h.) This change allows easier compilation,
as Lua compiles and works even if the package 'readline' is absent
from the system. Moreover, non-interactive uses don't load the library,
making the stand-alone slightly faster for small loads.

9904c253da Flexible limit for use of registers by constructors 
Instead of a fixed limit of 50 registers (which, in a bad worst case,
can limit the nesting of constructors to 5 levels), the compiler
computes an individual limit for each constructor based on how many
registers are available when it runs. This limit then controls the
frequency of SETLIST instructions.

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.)

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.

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.

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).
