Looks like a bit of code from Inventory Extensions viewer leaked into
release. This was supposed to prevent 'folder does not exist' spam as
Inventory Extensions does not create folders this way, instead it
blocked folder creation.

For unknown reason allocations of these coroutines often crash on client machines.
1. Limit quantity of coros running in parallel by reducing retries and wait time
2. Print out more diagnostic info

that unconditionally return. This eliminates the problem of pacifying a
compiler that expects a return statement vs. a compiler that detects that
callFail() unconditionally throws.

Thanks, Ansariel.

This one includes the fix for SL-19756.

This version eliminates references to the Windows wmic command, calling the
WMI API instead.

LLSDParam<LLSD> is the generic case, when we need to pass LLSDParam adapters
to some set of function parameters whose types we don't specifically know. Its
templated conversion operator notices the actual parameter type T and
delegates conversion to the specific LLSDParam<T> specialization.

But when T has picked up references, e.g. somewhere along the way in the
LL::apply() machinery, the compiler might not choose the desired conversion
because we don't have a sufficiently specific LLSDParam specialization.

LLSDParam<LLSD> can address that by using std::decay_t<T> when delegating to
the specific LLSDParam specialization. This removes references, const and
volatile.

There's a limit to how much time it's worth trying to work around a compiler
bug that's already been fixed in newer Xcode.

That wasn't the issue. This is a compiler bug:

This reverts commit c406fa7a.

Both the previous version and this compile and run successfully with Xcode
14.3.1, but our older TeamCity compiler chokes -- so we must iterate remotely,
sigh.

VC doesn't recognize that a constexpr name doesn't need to be bound into a
lambda. However, since it's knowable at compile time, it can be deduced within
the innermost lambda.

Replace deprecated event mask call (macOS)

replaces deprecated (since 10.12) reference to NSAnyEventMask with the replacement NSEventMaskAny. Functionality unaltered.

Major improvements to LLLeap functionality
