267ef461d0 Bug: check for constructor overflow in [exp] fields 
The check for constructor overflow was considering only fields with
explicit names, ignoring fields with syntax '[exp]=exp'.

d1ee2a4deb Bug: Bad error message with fields of string _ENV 
Errors with fields of the string _ENV (e.g., ("_ENV").u + 1) report
the error as comming from a global.

when closing a thread or a state.

983bc433e6 Bug: Use after free in 'luaV_finishset' 
If a metatable is a weak table, its __newindex field could be collected
by an emergency collection while being used in 'luaV_finishset'. (This
bug has similarities with bug 5.3.2-1, fixed in commit a272fa66.)

25da574fcb Bug: 'luaD_seterrorobj' should not raise errors 
This function can be called unprotected, so it should not raise any
kind of errors. (It could raise a memory-allocation error when creating
a message).

f5e55be2a0 Bug: Missing error status in panic function 
'luaD_throw' may call 'luaE_resetthread', which returns an error code
but clears 'L->status'; so, 'luaD_throw' should set that status again.

782ef85b22 Bug: wrong code gen. for indices with comparisons 
In function 'luaK_exp2val', used to generate code for indices: Macro
'hasjumps' does not consider the case when the whole expression is a
"jump" (a test). In all other of its uses, the surrounding code ensures
that the expression cannot be VJMP.

30982bec96 Bug: Bad stack manipulation in 'multiline' (REPL) 
'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.

1ab3208a1f 'lua.h' back to redundancy in version definitions 
Several tools inspect 'lua.h' to extract version information, and
they assume the file will have some specific format.

7eb1ed21b7 More permissive use of 'errno' 
Assume that no function will put garbage on errno (although ISO C allows
that). If any function during an operation set errno, and the operation
result in an error, assume that errno has something to say.

d5212c13b0 More disciplined use of 'errno' 
Set errno to zero before calling any function where we may use its
errno, and check errno for zero before using it (as functions may
not set it even in error).

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.

can overflow when we add the header.

842a83f09c Panic functions should not raise errors 
The standard panic function was using 'lua_tostring', which may raise
a memory-allocation error if error value is a number.

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).

81e4fce530 Simpler test in 'luaH_getint' 
The test whether key is inside the array part of a table uses a bit
trick to avoid computing the real size of the array part.

non UTF-8 test file (to test non UTF-8 sources).

6b51133a98 Thread stacks resized in the atomic phase 
Although stack resize can be a little expensive, it seems unusual to
have too many threads needing resize during one GC cycle. On the other
hand, the change allows full collections to skip the propagate phase,
going straight from a pause to the atomic phase.

09f3c2372f Option '-l' discards version sufix from file name

version suffix (everything after an hyphen) from a file name when
creating the module name.
