Introduce AlwaysReturn<void> specialization, which always discards any result
of calling the specified callable with specified args.
Derive new Windows_SEH_exception from LLException, not std::runtime_error.
Put the various SEH functions in LL::seh nested namespace, e.g.
LL::seh::catcher() as the primary API.
Break out more levels of Windows SEH handler to work around the restrictions on
functions containing __try/__except.
The triadic catcher() overload now does little save declare a std::string
stacktrace before forwarding the call to catcher_inner(), passing a reference
to stacktrace along with the trycode, filter and handler functions.
catcher_inner() accepts the stacktrace and the three function template
arguments. It contains the __try/__except logic. It calls a new filter_()
wrapper template, which calls fill_stacktrace() before forwarding the call to
the caller's filter function. fill_stacktrace(), in the .cpp file, contains
the logic to populate the stacktrace string -- unless the Structured Exception
is stack overflow, in which case it puts an explanatory string instead.
catcher_inner()'s __except clause passes not only the code, but also the
stacktrace string, to the caller's handler function. It wraps the caller's
handler function in always_return<rtype>(), where rtype is the type returned
by the trycode function. This allows a handler to return a value, while also
supporting the void handler case, e.g. one that throws a C++ exception. (This
is why we need AlwaysReturn<void>: some trycode() functions are themselves
void.)
For the dyadic catcher() overload, introduce common_filter() containing the
logic to distinguish a C++ exception from any other kind of Structured
Exception. The fact that the stacktrace is captured before the filter function
is called should permit capturing a stacktrace for a C++ exception as well as
for most other Structured Exceptions.
As before, the monadic catcher() overload supplies the rethrow() handler, in
the .cpp file.
Change existing calls from seh_catcher() to LL::seh::catcher().

Since August 2023, we've seen occasional GitHub Windows build test runs
terminate with 0xC00000FD: stack overflow. We've usually responded by bumping
up the default coroutine stack size.
On closer examination, it's always llleap_test.cpp that blows up that way --
and llleap_test.cpp doesn't appear to use coroutines at all. So apparently
we've been consuming more address space for ALL viewer coroutines without
actually addressing the problem.
Reset the default coroutine stack size to where it was before we started
bumping it up in response to these llleap_test.cpp stack overflow failures.
Note that LLCoros already catches and reports Windows structured exceptions,
underscoring that the observed stack overflow is not from within a coroutine.
While at it, restore the Windows llleap_test.cpp data volume to match Posix.
We think the problem that led to reducing that data volume was an APR bug,
which we hope has been fixed.
Equip test.cpp, the test driver program for all our TUT unit and integration
tests, with a Windows structured exception handler. Try to treat a Windows
structured exception as a test failure -- instead of silently terminating with
0xC00000FD. Moreover, when a structured exception occurs, output a stack trace
so we can try to track it down.

Remove all references to LLQueuedThread (but emulate a couple bits of its API
such as handle_t and getPending()).
Migrate ImageRequest into llimageworker.cpp. It has never been part of
LLImageDecodeThread's public API. Remove ImageRequest tests.
Remove all references to LLImageDecodeThread::pause(). The idea of pausing
another thread is bizarre to me, and LLThreadPool has no such operation. Nor
does it have an abortRequest().

On Mac, even if you run a test program with --debug or set LOGTEST=DEBUG, it
won't log to stderr if you're filtering build output or running the build in
an emacs compile buffer. This is because, on Mac, a viewer launched by mouse
rather than from the command line is passed a stderr stream that ultimately
gets logged to the system Console. The shouldLogToStderr() function is
intended to avoid spamming the Console with the (voluminous) viewer log
output. It tests whether stderr isatty() and, if not, suppresses calling
LLError::logToStderr().
This makes debugging test programs using log output trickier than necessary.
Change shouldLogToStderr() to permit logging when either stderr isatty() or is
a pipe. The original intention is preserved in that empirically, a viewer
launched by mouse is passed a stderr stream identified as a character device
rather than as a pipe.
Also introduce SetEnv, a class that facilitates setting (e.g.) LOGTEST=DEBUG
for specific test programs without setting it for all test programs in the
build. Using the constructor for a static object means you can set environment
variables before main() is entered, which is important because it's the main()
function in test.cpp that acts on the LOGTEST and LOGFAIL environment
variables.
These changes make it unnecessary to retain the temporary change in test.cpp
to force LOGTEST to DEBUG.

|

Sometimes it's useful to be able to temporarily override an existing LOGFAIL
setting in the current environment. It's far more convenient to prepend
LOGFAIL='' to a command than to 'unset LOGFAIL' as a whole separate command --
and then remember to restore its previous value.

The comments within indra/test/test.cpp promise that --debug is, in fact, like
LOGTEST=DEBUG. Until now, that was a lie. LOGTEST=level displayed log output
on stderr as well as in testprogram.log, while --debug did not.
Add LLError::logToStderr() function, and make initForApplication() (i.e.
commonInit()) call that instead of instantiating RecordToStderr inline. Also
call it when test.cpp recognizes --debug switch.
Remove the mFileRecorder, mFixedBufferRecorder and mFileRecorderFileName
members from SettingsConfig. That tactic doesn't scale.
Instead, add findRecorder<RECORDER>() and removeRecorder<RECORDER>() template
functions to locate (or remove) a RecorderPtr to an object of the specified
subclass. Both are based on an underlying findRecorderPos<RECORDER>() template
function. Since we never expect to manage more than a handful of RecorderPtrs,
and since access to the deleted members is very much application setup rather
than any kind of ongoing access, a search loop suffices.
logToFile() uses removeRecorder<RecordToFile>() rather than removing
mFileRecorder (the only use of mFileRecorder).
logToFixedBuffer() uses removeRecorder<RecordToFixedBuffer>() rather than
removing mFixedBufferRecorder (the only use of mFixedBufferRecorder).
Make RecordToFile store the filename with which it was instantiated. Add a
getFilename() method to retrieve it. logFileName() is now based on
findRecorder<RecordToFile>() instead of mFileRecorderFileName (the only use of
mFileRecorderFileName).
Make RecordToStderr::mUseANSI a simple bool rather than a three-state enum,
and set it immediately on construction. Apparently the reason it was set
lazily was because it consults its own checkANSI() method, and of course
'this' doesn't acquire the leaf class type until the constructor has completed
successfully. But since nothing in checkANSI() depends on anything else in
RecordToStderr, making it static solves that problem.
