Revamped environment variables again.
A previous commit changed how environment variables were managed.
Initially we were calling SetEnvironmentVariable() on each variable
defined in AppEnvironmentExtra prior to starting the service. That
behaviour was changed because it was technically incorrect, potentially
resulting in NSSM's own environment being harmed.
Unfortunately the changed method, creating a new environment block by
calling GetEnvironmentStrings() (or using the block from AppEnvironment
if that and AppEnvironmentExtra were both defined), failed if users did
something like set AppEnvironmentExtra to PATH=C:\bin;%PATH%. That
would result in the process being started with a block which included
TWO occurrences of the PATH variable; the system-defined one and the
appended one. The latter would be ignored, possibly causing the
application to fail to start.
For this third attempt we now call GetEnvironmentStrings() once at
startup, storing the block in a new variable which is only freed at
exit. Immediately prior to calling CreateProcess() to start the service
we use the new environment functions duplicate_environment() (on
AppEnvironment) and set_environment_block() (on AppEnvironmentExtra) to
set the variables. Then immediately after calling CreateProcess() we
call duplicate_environment() again to restore the original block.
Because they are passed to expand_environment_string(), the environment
blocks are subject to expansion. That means that setting PATH as
described in the example above would work. Trying to append items to
the PATH by setting AppEnvironment in a similar way will probably not
work.

set_environment_block() iterates through all the variables in an

clear_environment() removes all variables from the current environment.
duplicate_environment() duplicates an environment block by first calling

Fake stdin for applications which exit on EOF.
Some applications, like MonetDB server, expect to read commands on
stdin. If they read a keyword, usually "exit" or "quit" or if stdin is
closed, they will exit.
Such applications will typically work when run in a service context via
NSSM, as Windows will allocate a console window for them. However, when
the service is configured to redirect stdout and/or stderr but not
stdin, the application will exit immediately because it will see no
input and think that the user closed stdin.
To deal with this situation we interpret an AppStdin value of "|" (a
single pipe character) as requesting a hack mode whereby we open a pipe
and pass the reading end to the application as the stdin handle. We
never actually write anything to the writing end of pipe but simply keep
it around until the application exits or the service receives a stop
control. Closing the pipe on receipt of a stop request may even be
sufficient to close the application gracefully without resorting to any
of the other stop methods.
As an aside, MonetDB server can be run in batch mode, wherein it does
not attempt to read from stdin at all. The hack is not necessary for it

Copy environment block rather than setting extra variables.
If AppEnvironmentExtra is configured we were calling
SetEnvironmentVariable() to append each one to the existing environment.
That's arguably wrong as it could mess up NSSM's own environment.
Instead we now call GetEnvironmentStrings() and take a copy of the
current environment ebfore appending the extra environment as we were
doing before.

Force UTF-16 output.
If we were compiled as a Unicode application, set stdout and stderr
output mode to UTF-16 text. Doing so allows French and Italian accented
characters to show up correctly on the console.
We currently have no analogous method for fixing the output of NSSM when
compiled as an ANSI application.

Added mandatory restart delay.
The REG_DWORD AppRestartDelay entry specifies a minimum number of
milliseconds by which we will delay the restart (not the initial start)
of the managed application. If the application exited soon enough to
trigger throttling, the actual delay will be whichever is longer of
AppRestartDelay and the calculated throttle time.

Give up on older Visual Studio versions.
Tests show that Visual Studio 6 and 2005 won't build NSSM presumably
because there is no suitable platform SDK corresponding to those versions.
Carting around a legacy DSP and DSW file is therefore somewhat
pointless, especially as newer Visual Studio releases have freely
available Express versions and will compile the project.

Legacy quick'n'dirtiness.
On Windows 2000, StartService() and ControlService() return
ERROR_IO_PENDING immediately. Later versions of Windows have a
builtin timeout before they will return that error.
As far as we're concerned, ERROR_IO_PENDING indicates that the service
control was sent successfully so we simply override the error and
return success.
If NSSM's service management functionality is ever expanded we can take
the time to handle service controls in a more robust way.

New function to open a service either by name or display name. Since no

OpenService() expects a service name so if it fails with status
ERROR_SERVICE_DOES_NOT_EXIST we can enumerate all services and look for
one whose display name matches the argument passed to open_service(),
and open it. As a side effect we can optionally store the canonical
