e3ce88c9e8 New function 'lua_numbertostrbuff' 
It converts a Lua number to a string in a buffer, without creating
a new Lua string.

cd4de92762 Maximum stack size may not fit in unsigned short 
Therefore, fields ftransfer/ntransfer in lua_Debug must have type
'int'. (Maximum stack size must fit in an 'int'.) Also, this commit
adds check that maximum stack size respects size_t for size in bytes.

52aa2b5d24 Details 
- 'unsigned int' -> 'unsigned'
- Some explicit casts to avoid warnings
- Test avoids printing the value of 'fail' (which may not be nil)

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.)

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.

6443185167 "Emergency" new version 5.4.6 
'lua_resetthread' is back to its original signature, to avoid
incompatibilities in the ABI between releases of the same version.
New function 'lua_closethread' added with the "correct" signature.

5a04f1851e New function 'luaL_makeseed'

and 'table.sort' that tries to create a value with a minimum level
of randomness.

cc1692515e New API function 'lua_closeslot' 
Closing a to-be-closed variable with 'lua_settop' is too restrictive,
as it erases all slots above the variable. Moreover, it adds side
effects to 'lua_settop', which should be a fairly basic function.

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.

b56d4e570a Changes in the warning system 
- The warning functions get an extra parameter that tells whether
message is to be continued (instead of using end-of-lines as a signal).

- The user data for the warning function is a regular value, instead
of a writable slot inside the Lua state.

437a5b07d4 Added a warning system to Lua

to the programmer that do not interfere with the running program.

fdc25a1ebf New functions 'lua_resetthread' and 'coroutine.kill' 
New functions to reset/kill a thread/coroutine, mainly (only?) to
close any pending to-be-closed variable. ('lua_resetthread' also
allows a thread to be reused...)

5fda30b4f9 'lua_toclose' gets the index to be closed as an argument 
Sometimes it is useful to mark to-be-closed an index that is not
at the top of the stack (e.g., if the value to be closed came from
a function call returning multiple values).

b8fed93215 New syntax for to-be-closed variables 
The new syntax is <local *toclose x = f()>. The mark '*' allows other
attributes to be added later without the need of new keywords; it
also allows better error messages.  The API function was also renamed
('lua_tobeclosed' -> 'lua_toclose').
