Seek to end of large files correctly.
The documentation for SetFilePointer() is potentially confusing. When the
third argument is NULL, the second argument is treated as a 32-bit
offset to move the pointer. When the third argument is not NULL, it is
a pointer to an unsigned integer representing the high order part of a
64-bit signed offset, and the second argument is treated as the
corresponding (signed) low order part.
The documentation states that "if you do not need the high order
32-bits" the third argument must be NULL, and indeed we were setting it
to NULL on the basis that we were moving 0 bytes from FILE_END and 0 can
most definitely be represented in 32-bits.
However in practice when seeking to the end of a file whose size cannot
be represented in 32-bits we actually need to use a 64-bit offset, even
though the 64-bit integer we use is 0. So we must pass a pointer to a
zeroed high part.
Note that when SetFilePointer() succeeds the return value is the low
order part of the actual offset and the high order value is filled with
the high order offset, which has two important implications. Firstly we
cannot simply declare our zero variable statically but must pass a new
value each time. Secondly it is insufficient to check that the function
returned something other than INVALID_SET_FILE_POINTER, as we were
doing; instead we must treat that return value as success if and only
iff GetLastError() returns NO_ERROR.
Marcin Lewandowski noticed that large files were not always appended
correctly. Because we were passing NULL as the third argument to
SetFilePointer() it returned INVALID_SET_FILE_POINTER and we didn't call
SetEndOfFile().
SetFilePointerEx() is supported on all versions of Windows we target,
and has a much simpler definition than SetFilePointer(). We now use
that instead.

paused.
Don't accept any control until startup is pending.
Don't accept any control after processing a stop control.

Refactor kill functions to be independent of services.
Removed most explicit references to service data in kill functions so
they can be used to kill arbitrary process trees.
The function to wait for service status change has been renamed
await_single_handle() to reflect that it can wait for any single object
not just a service's process handle.

Single waiting function.
Use a single function to wait for service status to change, regardless
of if we are waiting for the service to run for a minimum period of time
to be unthrottled or for it to shut down..

Allow slow service startup again.
Previously we enforced a maximum delay in reporting to the service
manager that the service was started, and waited for the application to
become unthrottled in the background.
Users may prefer that the service not report a started state until the
application is unthrottled. Therefore we now loop and increment the
status checkpoint and wait hint to satisfy the service manager that we
aren't hung.
Thanks Tom Saul.

Copy/truncate file rotation.
Some processes, notably Logstash, open files for reading without setting
the FILE_SHARE_READ share mode. If NSSM is using such a file for I/O
redirection and it tries to rotate the file, its MoveFile() call will
fail.
If the new (REG_DWORD) value(s) AppStdoutCopyAndTruncate and/or
AppStderrCopyAndTruncate are non-zero, NSSM will instead try to rotate
the file(s) by calling CopyFile() to create a copy of the file then
calling SetEndOfFile() to truncate the original file to zero size.
Doing so allows the rotation to succeed at the cost of time and disk
space to create a full copy of the file.
If the new (REG_DWORD) value AppRotateDelay is non-zero, NSSM will sleep
for the given number of milliseconds after rotation, regardless of the
rotation method used. Testing with Logstash specifically has shown that
introducing a delay of 1000ms may be sufficient to avoid an issue
whereby the reading application loses the final line of input from the
old file due to not noticing that it has been truncated.
Thanks Miguel Angel TerrĂ³n.
