15231d4fb2 'nresults' moved into 'callstatus' 
That gives us more free bits in 'callstatus', for future use.

55ac40f859 Cleaning of llimits.h 
Several definitions that don't need to be "global" (that is, that
concerns only specific parts of the code) moved out of llimits.h,
to more appropriate places.

9fa63a6268 Some 'unsigned int' changed to 'unsigned' 
'unsigned int' is too long sometimes. (We already write 'long' instead
of 'long int'...)

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' 
This function unifies code from 'lua_newstate', 'math.randomseed',
and 'table.sort' that tries to create a value with a minimum level
of randomness.

bfbff3703e Bug: Wrong status in coroutine during reset 
When closing variables during 'coroutine.close' or 'lua_resetthread',
the status of a coroutine must be set to LUA_OK; a coroutine should
not run with any other status. (See assertion in 'lua_callk'.)

After the reset, the status should be kept as normal, as any error
was already reported.

1537d6680b New control for reentrancy of emergency collections 
Instead of assuming that shrinking a block may be an emergency
collection, use an explicit field ('gcstopem') to stop emergency
collections while GC is working.

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).

4e47f81188 New implementation for to-be-closed variables 
To-be-closed variables are linked in their own list, embedded into the
stack elements. (Due to alignment, this information does not change
the size of the stack elements in most architectures.)  This new list
does not produce garbage and avoids memory errors when creating tbc
variables.

6ccd24eff5 Simpler handling of errors when creating tbc variables 
New field 'lua_State.ptbc' keeps to-be-closed variable until its
upvalue is created, so that it can be closed in case of a
memory-allocation error.

b07fc10e91 Allow yields inside '__close' metamethods 
Initial implementation to allow yields inside '__close' metamethods.
This current version still does not allow a '__close' metamethod
to yield when called due to an error. '__close' metamethods from
C functions also are not allowed to yield.

6188f3a654 Reset thread before panicking 
Before panicking, it is simpler to reset the thread instead of closing
its variables and adjust the top manually.

7af27ef59d Cleaner handling of errors in '__close' metamethods

entire call to 'luaF_close'.

409256b784 'coroutine.close'/'lua_resetthread' report original errors 
Besides errors in closing methods, 'coroutine.close' and
'lua_resetthread' also consider the original error that stopped the
thread, if any.

65d2294454 Changed access to global table in the registry 
The global table is always in the array part of the registry; we can
use this fact to make its access slightly more efficient.

d282652561 Bug when growing a stack 
When a stack grows, its extra area can be in use, and it becomes part
of the common area. So, the extra area must be kept correct all the
times. (Bug introduced by commit 5aa36e894f5.)

9a89fb1c9d Hash always use all characters in a long string 
Hashes for long strings are computed only when they are used as keys
in a table, not a too common case. And, in that case, it is to easy to
force collisions changing only the characters which are not part of the
hash.

5aa36e894f No more field 'lua_State.stacksize' 
The stack size is derived from 'stack_last', when needed. Moreover,
the handling of stack sizes is more consistent, always excluding the
extra space except when allocating/deallocating the array.
