852db64d91 Dynamically load WINMM, remove USER32
Prevent loading more libraries than necessary, so load WINMM the first
time the bell is used and use the CRT printf functions to avoid loading
USER32 at all.

I was also going to remove MSVCRT, but that turned out to be more
trouble than it's worth.  However, a side-effect that I kept is
replacing bsearch with a dedicated search routine.

aa8b0c6a36 Use the system default sound for the bell
Windows 7 uses Beep for the bell, which means if you accidentally view
a binary file, the console freezes until all the bells have finished.
Windows 10 uses PlaySound, which avoids the freeze, but prevents the
sound being played at all if the program immediately exits (in its own
host).	This uses PlaySound in its own thread, ignoring additional bells
whilst one is currently playing and waiting for it to finish before
terminating.

bd696b55c8 Exclude entire programs; better hooking of dynamically-loaded libraries.
ANSICON_EXC can now be used to exclude an entire program (including children).
This is achieved by simply not specifying an extension: ANSICON_EXC=program.exe
will just ignore program.exe (its DLLs will still be hooked, as will its child-
ren), but ANSICON_EXC=program will not hook program at all (which also means
its children will not be hooked).

The various LoadLibrary hooks would only hook the DLL that was specified - any
DLLs it loaded would be missed.  That has now been rectified.  Similarly, a DLL
that is injected via CreateRemoteThread, using LoadLibraryA or LoadLibraryW as
its ThreadProc, will now be hooked.

dc7569dc26 Inject by adding to the Import Directory Table.
-p uses CreateRemoteThread, determining kernel32.dll & LLW dynamically.
Loading via LoadLibrary will remember the current attributes, restoring them on
unload.
Tweaked log output (remove quotes around CreateProcess command line; add an
underscore to 64-bit addresses).
ansicon.exe will really output (to the console) strings as Unicode.
Fixed ansicon.exe, if installed, restoring the default attributes, not current.
ansicon.exe will start with ANSICON_DEF (if defined and -m not used).

a52a46c9c1 New method to obtain 32-bit LoadLibraryW from 64-bit code, eliminating the need
for ANSI-LLW.exe.
Set the code page so ansicon.exe can display some strings properly.
Expand wildcards for -t.
VC6 can now compile the 32-bit version; use it for the release binaries.
Improvements to the VC makefile.
Describe the sequences in a bit more detail.

790de57763 Exclude modules from being hooked; hook only selected GUI programs.
Added environment variable ANSICON_EXC to specify modules that should not be
hooked.  This should work around the nvd3d9wrap.dll issue.  Since it helps to
know what the modules are, logging is now always available, controlled by -l
or ANSICON_LOG.  A side-effect caused debugstr.c to move to util.c.

GUI programs are once again not hooked, unless run by "ansicon" directly or in
the ANSICON_GUI environment variable.  Since not hooking still leaves ANSICON in
the environment, created ANSICON_VER as a dynamic-only variable, which can also
serve as a version check.

Due to an email requesting a reverse video option, realised I always take the
current attributes as default.	This means if you turned on reverse and ran a
program, it would take the reverse as its default.  Created ANSICON_DEF variable
to explicitly set the default attribute, using the current if it doesn't exist.
The reverse video option is done via a "negative" attribute (e.g. "-m-f0" is
reversed black on white, meaning you'll get white on black, with foreground
sequences changing the background).  (The difference from "\e[7m" is that it
won't be reset on "\e[m".)

A child program will inherit the parent's modes (but not shift); the parent will
read the child's modes on exit (but not unload).  The exception is "ansicon",
which will always start with the default modes and leave the parent unchanged.

Improved the AutoRun entry, only running "ansicon" if ANSICON_VER doesn't exist.
The "ansicon" command is always first.

Stopped -u implying -p; return the program's exit code; don't restore the
original color when just using -p; output error messages to stderr.
