Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.

Eliminate not used includes and replace some more includes
with forward declarations where appropriate.

fixes AddressSanitizer: stack-buffer-underflow on address 0x7ffd9a375820 at pc 0x555ac9721b4e bp 0x7ffd9a374e70 sp 0x7ffd9a374620
Backend registry holds a unique pointer to the backend implementation
that must outlive the whole tracing lifetime until the shutdown call.
So it must be catched/moved before the program exits its scope by
passing out the lambda chain.
Regarding deletion of the default destructor: moving object requires
a move constructor (for do_with) that is not implicitly provided if
there is a user-defined object destructor defined even tho its impl
is default.
