[3.7] bpo-39389: gzip: fix compression level metadata (GH-18077) (GH-18101)
 
* bpo-39389: gzip: fix compression level metadata (GH-18077)

As described in RFC 1952, section 2.3.1, the XFL (eXtra FLags) byte of a
gzip member header should indicate whether the DEFLATE algorithm was
tuned for speed or compression ratio. Prior to this patch, archives
emitted by the `gzip` module always indicated maximum compression.
(cherry picked from commit eab3b3f1c60afecfb4db3c3619109684cb04bd60)

/* pydtrace_probes.h, on systems with DTrace, is auto-generated to include
   `PyDTrace_{PROBE}` and `PyDTrace_{PROBE}_ENABLED()` macros for every probe
   defined in pydtrace_provider.d.

   Calling these functions must be guarded by a `PyDTrace_{PROBE}_ENABLED()`
   check to minimize performance impact when probing is off. For example:

       if (PyDTrace_FUNCTION_ENTRY_ENABLED())
           PyDTrace_FUNCTION_ENTRY(f);
