- Reinstate gconv-modules as the default configuration file
This adds patches proposed upstream to enable downgrades across
major glibc versions.
File list construction and the find-debuginfo.sh wrapper had
to be adjusted to cope with the changed file name patterns.
Auto-sync Upstream commit: ebae2f5a6f971a8f0b6c99e00f9c45ef7433924a
Changes in addition to the sync:
Add a downstream patch[1] to reinstate gconv-modules file and apply
glibc-rh697421.patch after it. Also update spec file to create a new
package glibc-gconv-extra with iconv converter modules that are not
commonly used so that they can be removed in minimal or hardened
installations.

Upstream commit: ac0353af81a23535f517586a5d04427120a157ac
- This removes libpthread as a separate shared object. New programs
will depend on the GLIBC_2.34 symbol version. Upstream development
brings in the following noteworthy bug fixes:
- ppc64le: scv ABI error handling fails to check IS_ERR_VALUE (#1962971)
- CVE-2021-27645 glibc: Use-after-free in addgetnetgrentX function in
netgroupcache.c (#1932590)
- Linking the main program with jemalloc causes sysconf to deadlock in
audit mode (#1909920)
Glibc on arm has a memory tagging option that can be enabled
via GLIBC_TUNABLES="glibc.mem.tagging=$SOMETHING" when glibc
is built with memory tagging support and the kernel/HW supports
MTE. This should be side effect free unless the user turns it
on with approprate HW support.

This needs a wrapper script around find-debuginfo.sh, so that
ld.so is not stripped.
This commit resolves debuginfo file conflicts (#1886295) because
the ldconfig debuginfo file now includes the architecture name.
All debugging information is preserved in ld.so (#1905611). With
the distribution defaults, we strip all binaries again (#1661510).

The info pages of The GNU C Library Reference Manual included in the
devel subpackage, were (slightly) increasing the installed size of
systems that required the devel object files but not the manual.
In addition to this, a number of unnecessary files (READMEs, NEWS,
INSTALL, and an example gai.conf) were included in either the main
package or the common subpackage.
This commit introduces a new glibc-doc.noarch subpackage and moves the
info pages from the devel subpackage and the debugger interface
documentation from the main package into glibc-doc. It also removes all
the unnecessary documentation-like files mentioned above.
nscd is planned for a phased removal, with deprecation in Fedora 34:
https://fedoraproject.org/wiki/Changes/DeprecateNSCD
... and removal in Fedora 35:
https://fedoraproject.org/wiki/Changes/RemoveNSCD
systemd-resolved is now enabled by default for DNS caching in Fedora,
and sssd is capable of caching the remaining named services that nscd
handles. It is therefore time to retire nscd in Fedora and move to more
modern named services caches.
