Issue #26588:
* The _tracemalloc now supports tracing memory allocations of multiple address
spaces (domains).
* Add domain parameter to tracemalloc_add_trace() and
tracemalloc_remove_trace().
* tracemalloc_add_trace() now starts by removing the previous trace, if any.
* _tracemalloc._get_traces() now returns a list of (domain, size,
traceback_frames): the domain is new.
* Add tracemalloc.DomainFilter
* tracemalloc.Filter: add an optional domain parameter to the constructor and a
domain attribute
* Sublte change: use Py_uintptr_t rather than void* in the traces key.
* Add tracemalloc_config.use_domain, currently hardcoded to 1
* Various sections were pointing to the section on the string.Formatter
class, when the section on the common format string syntax is probably more
appropriate
* Fix references to various format() functions and methods
* Nested replacement fields may contain conversions and format specifiers,
and this is tested; see Issue #19729 for instance
The concept of .pyo files no longer exists. Now .pyc files have an
optional `opt-` tag which specifies if any extra optimizations beyond
the peepholer were applied.
