84e32ad2eb Added opcodes for arithmetic with K operands 
Added opcodes for all seven arithmetic operators with K operands
(that is, operands that are numbers in the array of constants of
the function). They cover the cases of constant float operands
(e.g., 'x + .0.0', 'x^0.5') and large integer operands (e.g.,
'x % 10000').

e073cbc2e5 Better error messages for invalid operands in numeric 'for' 
"Better" and similar to error messages for invalid function arguments.
  *old message: 'for' limit must be a number
  *new message: bad 'for' limit (number expected, got table)

f99509581e Removed extra information from RCS keyword strings 
Version numbers and dates (mostly wrong) from RCS keyword strings
removed from all source files; only the file name are kept.

e64e20ac81 minimizing the code ran by 'vmfetch' + no more 'vra' 
(the code is simpler without 'vra' and conversion is a no-op)

4907444db9 'fTransfer' -> 'ftransfer' / 'nTransfer' -> 'ntransfer'

422318f677 two new fields 'fTransfer'/'nTransfer' in 'lua_Debug' structure

b1379936cf vararg back to '...' (but with another implementation) 
new implementation should have zero overhead for non-vararg functions

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

b3f924bc69 'Proto->numparams' does not include vararg parameter

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.)

9fa1baf6de opcodes for order and shift can use several metamethods, 
so it is better to use a generic description + metamethod names
in some error messages shown without '__' prefix

196c87c9ce no more 'stackless' implementation; 'luaV_execute' calls itself 
recursively to execute function calls. 'unroll' continues all
executions suspended by an yield (through a long jump)

5440b42f43 using 'trap' to stop 'luaV_execute' when necessary (tracing and

b42430fd3a 'lineinfo' in prototypes saved as differences instead of absolute 
values, so that the array can use bytes instead of ints, reducing
its size. (A new array 'abslineinfo' is used when line differences
do not fit in a byte.)
