[PATCH 00/15] Sync Linux definitions up to Linux 7.1

[Adhemerval Zanella]

This patchset updates the Linux-specific glibc headers, syscall lists, and
constant tests to match the definitions introduced up to Linux 7.1 (the
latest released kernel), covering the 6.18, 6.19, 7.0, and 7.1 merge
windows.

This series also fixes netinet/tcp.h: the struct tcp_info tail synced by
commit 7e46c2aae47 was mis-encoded as two uint16_t fields, dropping
tcpi_ecn_mode and tcpi_options2; it is restored to the kernel bitfield
layout (size unchanged) and the TCPI_ECN_MODE_/TCP_ACCECN_ value
constants are added.

Kernel-internal or clone3-only definitions that glibc does not export
(PIDFD_AUTOKILL, the high CLONE_/UNSHARE_EMPTY_MNTNS flags, STATMOUNT_BY_FD,
the PR_CFI_/PR_RSEQ_SLICE_* prctls) are intentionally left out.
