8691612f01 when calling a hook, cannot decrease 'ci->top' (to preserve stack

'isOT' instructions)

1d5b885437 when running Lua code, there is no need to keep 'L->top' "correct";
set it only when needed.

4dc0be950a new macro 'isLuacode' (to distinguish regular Lua code from
hooks, where C code can run inside a Lua function).

3153a41e33 no need to save 'pc' in case of allocation errors

7024f49c42 default now is compiling without compatibility options + smaller
stack size in debug mode (clang uses still more stack space when
debugging).

e752d84ed8 bug: memory-allocation error when resizing a table can leave it

86431a2f1c new opcodes BANDK/BORK/BXORK. (They do not use immediate operands
because, too often, masks in bitwise operations are integers larger
than one byte.)

36cf8f3a3c Code should not change the stack level after the initialization of a
string buffer.

725c15a4ca when shrinking stack, always shrinks the CI list.
(Stack overflow is not corelated to CI overflow anymore.)

b077b20206 back to reallocation when resizing the string table.
(Not a good idea to explicitly allocate new memory when shrinking
something.)

7ad20af2cf more freedom in handling memory-allocation errors (not all allocations
automatically raise an error), which allows fixing a bug when resizing
a table.

c5ebed7399 'luaM_shrinkvector' raises an error if it cannot shrink the block
(several parts of Lua use array size in protos as proxies for
number of valid elements)

9d28b40152 rehashes string table always allocating a new array instead of
reallocating old one. (Avoids problems if reallocation to a small
size fails.)
