Linux 5.13 adds a PTRACE_GET_RSEQ_CONFIGURATION constant, with an
associated ptrace_rseq_configuration structure.
Add this constant to the various sys/ptrace.h headers in glibc, with
the structure in bits/ptrace-shared.h (named struct
__ptrace_rseq_configuration in glibc, as with other such structures).
In Kunpeng-920, the performance of strcmp deteriorates only
when the 16 to 23 characters are different.Or the string is
only 16-23 characters.That shows 2 misses per iteration which
means this is a branch predictor issue indeed.
In the preceding scenario, strcmp performance is 300% worse than expected.
Fortunately, this problem can be solved by modifying the alignment of the functions.

The default debuginfo management mechanism is not deleted.
Instead, Use the default macro of RPM.
/usr/lib/rpm/openEuler/macros defines:
"""
%install% {?_Enable Debug Package:% {?Build subdirectory:% {debug package}\
%%Install\
%{nil}
"""
There are two changes:
1. The source files in /usr/src are
correctly packed into the debugging source.
2. The debugging file contains the glibc version number.
The CI detects the file change. However, I think this is caused by the CI.

AF_NETLINK support is not quite optional on modern Linux systems
anymore, so it is likely that the first attempt will always succeed.
Consequently, there is no need to cache the result. Keep AF_UNIX
and the Internet address families as a fallback, for the rare case
that AF_NETLINK is missing. The other address families previously
probed are totally obsolete be now, so remove them.
Use this simplified version as the generic implementation, disabling
Netlink support as needed.
