Implement the IMM function table in module user32.dll. CORE-11700
File immtable.h is located at win32ss/user/user32/include, that is a list of the DEFINE_IMM_ENTRY macro calls.
Improve IP address controls.
- Set focus to EDIT control to show caret.
- Process WM_GETDLGCODE messages on EDIT control to catch Tab key.
- Process Tab key and Shift+Tab key in processing WM_KEYDOWN.
CORE-3479
- Detect whether a division by zero is done, and fail if so.
- Detect whether an invalid number is provided:
* If _tcstol() fails with errno == ERANGE, we've got an overflow or
underflow.
* If the next character where _tcstol() is not a whitespace but is a
character compatible with the first character of an identifier, the
number is invalid.
- Add + to the list of existing unary operators (!,~,-), and parse them
where many of these are present. Indeed, expressions like: +3, -+-+3,
!!-+3 (or with other unary ops, etc.) are valid.
- Operators constituted of more than one characters, can contain
whitespace separating their constituting characters.
Thus, "a + = 3" is equivalent to "a += 3" (and the same for -=, *=,
/=, %=, &=, |= and ^=), and "a < < 3" is equivalent to "a << 3" (and
the same for >>, <<= and >>=).
- After evaluating everything, if unparsed data remains, fail and bail out.
- Return Windows' CMD-compatible errorlevels.

Fixes some cmd_winetests.
Observation shows that this is done only when the top-level batch file
is being run (and then terminates); the echo flag is not restored to its
previous state when a child batch file terminates and gives main back to
its parent batch.
- Make sure that non-administrator users can list associations, and
display appropriate error messages when e.g. they don't have sufficient
privileges to perform an operation.
- Make the helper functions all return Win32 values, used as the
ERRORVALUE, except when a specific extension association fails to be
displayed, in which case the ERRORVALUE is normalized to 1.
- Since the 'param' is a modifiable string (that can be modified by the
command, independently of the way it's called), just use it to isolate
the extension by zeroing out the equls-sign separator.
Commands APPEND/DPATH and FTYPE are also concerned by this; however
we do not implement them in our CMD.EXE yet.
These commands set the ERRORLEVEL differently, whether or not they are
run manually from the command-line/from a .BAT file, or from a .CMD file:
- From command-line/.BAT file, these commands set the ERRORLEVEL only if
an error occurs. So, if two commands are run consecutively and the first
one fails, the ERRORLEVEL will remain set even if the second command
succeeds.
- However, when being run from a .CMD file, these command will always
set the ERRORLEVEL. In the example case described above, the second
command that succeeds will reset the ERRORLEVEL to 0.
This behaviour is determined from the top-level batch/script file being
run. This means that, if a .BAT file is first started, then starts a
.CMD file, the commands will still behave the .BAT way; on the opposite,
if a .CMD file is first started, then starts a .BAT file, these commands
will still behave the .CMD way.
To implement this we introduce one global BATCH_TYPE enum variable that
is initialized to the corresponding batch/script file type when the
top-level script is loaded. It is reset to "none" when that script
terminates.

Replace call to AllocatedBufferSize(), with BufferSize().
Indeed (quoting https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/portcls/nf-portcls-idmachannel-buffersize ):
> The BufferSize() method returns the buffer size that was set by the previous call to IDmaChannel::SetBufferSize(). If SetBufferSize() has not been called since the IDmaChannel::AllocateBuffer() call, BufferSize returns the allocated buffer size. The DMA-channel object does not actually use this value internally. This value is maintained by the object to **allow its various clients to communicate the intended size of the buffer**.
And this is exactly what we want to do.
This compatibility behaviour implements the buggy behaviour of FOR /F
token parsing that can be observed in Windows' CMD, and that is tested
by the cmd_winetests.
It can be disabled at compile time via the MSCMD_FOR_QUIRKS define.
It fixes additional cmd_winetests, in concert with commit cb2a9c31.
Explanation of the implemented buggy behaviour
==============================================
In principle, the "tokens=x,y,m-n[*]" option describes a list of token
numbers (must be between 1 and 31) that will be assigned into variables.
Theoretically this option does not cumulate: only the latest 'tokens='
specification should be taken into account.
However things are not that simple in practice. First, not all of the
"tokens=" option state is reset when more than one specification is
provided. Second, when specifying a token range, e.g. "1-5", Windows'
CMD just ignores without error ranges that are not specified in
increasing order. Thus for example, a range "5-1" is ignored without
error. Then, token numbers strictly greater than 31 are just ignored,
and if they appear in a range, the whole range is ignored.
Another bug is the following one: suppose that the 'tokens'
specification reads:
"tokens=1-5,1-30" , or: "tokens=1-5,3" ,
i.e. more than one range, that overlap partially. Then the actual total
number of variables will not be of the larger range size, but will be
the sum, instead.
Thus, in the first example, a total of 5 + 30 == 35 variables (> 31) is
allocated, while in the second example, a total of 5 + 1 == 6 variables
is allocated, even if they won't all store data !!
In the first example, only the first 30 FOR variables will be used, and
the 5 others will contain an empty string. In the second example, only
the first 5 FOR variables will be used, and the other one will be empty.
We also see that due to that, the "Variables" buffer of fixed size
cannot always be used (since it can contain at most 32 variables).
Last but not least, when more than one "tokens=" specification is
provided, for example:
"tokens=1-31 tokens=1-20"
a total number of 31 FOR variables (because 31 is the max of 31 and 20)
is allocated, **but** only 20 are actually used, and the 11 others
return an empty string.
And in the specification: "tokens=1-31,* tokens=1-20", a total of
31 + 1 + 20 = 52 variables is initialized, but only the first 20 will
be used, and no "remaining-line" token (the '*' one) is used.
