59c88f846d Broadening the use of branch hints 
More uses of macros 'likely'/'unlikely' (renamed to
'l_likely'/'l_unlikely'), both in range (extended to the
libraries) and in scope (extended to hooks, stack growth).

38cc7d40a4 Bug: cannot allow the call 'debug.getinfo(0, ">")' 
A 'what' argument starting with '>' indicates that there is a function
in the C stack, which won't be there if the first argument is not a
function.

364e569945 Avoid calling 'fprintf' with NULL 
Avoid undefined behavior in calls like «fprintf("%s", NULL)».
('lua_writestringerror' is implemented as 'fprintf', and 'lua_tostring'
can return NULL if object is not a string.)

6eb53b7526 Details 
Several details in code (e.g., moving a variable to the most inner
scope that encloses its uses), comments, parameter names, extra tests.

03cde80b58 'setCstacklimit' renamed to 'setcstacklimit'

b96b0b5abb Added macro 'luaL_pushfail' 
The macro 'luaL_pushfail' documents all places in the standard libraries
that return nil to signal some kind of failure. It is defined as
'lua_pushnil'. The manual also got a notation (@fail) to document those
returns. The tests were changed to be agnostic regarding whether 'fail'
is 'nil' or 'false'.

3c0d3c6fbe Avoid using addresses of static variables as unique keys 
The addresses of static variables may be different for different
instances of Lua, making these instances incompatible if they use
these addresses as unique keys in the registry (or other tables).

be73f72fcc New function 'setCstacklimit' 
Added new functions to dynamically set the C-stack limit
('lua_setCstacklimit' in the C-API, 'debug.setCstacklimit' in Lua).

5ca1075b71 Added field 'srclen' to structure 'lua_Debug' 
This new field gets the length of 'source' in the same structure.
Unlike the other strings in that structure, 'source' can be
relatively large, and Lua already has its length readily available.

46beca5bed Better error messages for some polymorphic functions 
New auxiliary functions/macros 'luaL_argexpected'/'luaL_typeerror'
ease the creation of error messages such as

  bad argument #2 to 'setmetatable' (nil or table expected, got boolean)

(The novelty being the "got boolean" part...)

f99509581e Removed extra information from RCS keyword strings

removed from all source files; only the file name are kept.

Old luaL_register will be deprecated.
