f92b77ff0d Change the isc_thread_self() return type to uintptr_t
The pthread_self(), thrd_current() or GetCurrentThreadId() could
actually be a pointer, so we should rather convert the value into
uintptr_t instead of unsigned long.

45c55b1e7e Add isc_trampoline API to have simple accounting around threads
The current isc_hp API uses internal tid_v variable that gets
incremented for each new thread using hazard pointers.  This tid_v
variable is then used as a index to global shared table with hazard
pointers state.  Since the tid_v is only incremented and never
decremented the table could overflow very quickly if we create set of
threads for short period of time, they finish the work and cease to
exist.  Then we create identical set of threads and so on and so on.
This is not a problem for a normal `named` operation as the set of
threads is stable, but the problematic place are the unit tests where we
test network manager or other APIs (task, timer) that create threads.

This commits adds a thin wrapper around any function called from
isc_thread_create() that adds unique-but-reusable small digit thread id
that can be used as index to f.e. hazard pointer tables.  The trampoline
wrapper ensures that the thread ids will be reused, so the highest
thread_id number doesn't grow indefinitely when threads are created and
destroyed and then created again.  This fixes the hazard pointer table
overflow on machines with many cores. [GL #2396]

b1a7ec7481 Remove isc_thread_key API in favor of ISC_THREAD_LOCAL variables
For BIND 9.16+, TLS aware compiler is required, and using
ISC_THREAD_LOCAL is preferred way of using Thread Local Storage.  The
isc_thread_key API is no longer used anywhere and hence was removed from
BIND 9.

01731d4b1b Add and use ISC_THREAD_LOCAL macro
The new ISC_THREAD_LOCAL macro unifies usage of platform dependent
Thread Local Storage definition thread_local vs __thread vs
__declspec(thread) to a single macro.

The commit also unifies the required level of support for TLS as for
some parts of the code it was mandatory and for some parts of the code
it wasn't.

46919579bb Make isc_thread_join() assert internally on failure
Previously isc_thread_join() would return ISC_R_UNEXPECTED on a failure to
create new thread.  All such occurences were caught and wrapped into assert
function at higher level.  The function was simplified to assert directly in the
isc_thread_join() function and all caller level assertions were removed.
