Backport lttng-tools (2.13.11 -> 2.14.0) and lttng-ust (2.13.6 -> 2.14.0) from the Azure Linux 4.0 branch to enable the per-channel buffer allocation policy (lttng enable-channel --buffer-allocation=per-channel), keeping trace buffer/disk usage independent of CPU count on high-vCPU SKUs. - lttng-tools: bump to 2.14.0; add gcc-c++ BuildRequires (2.14 requires a C++ compiler); require userspace-rcu >= 0.14.0 (already shipped on 3.0); pin lttng-ust to the 2.14 ABI series (>= 2.14.0, < 2.15.0). - lttng-ust: bump to 2.14.0; update source signature. - lttng-consume: Release bump to rebuild against the liblttng-ust-ctl soname change (.so.5 -> .so.6); liblttng-ust.so.1 is unchanged. - cgmanifest.json: update lttng-tools and lttng-ust component entries.

lttng-tools 2.14 fails to compile against userspace-rcu 0.14.0 with 'need typename before std::remove_cv<...>::type' because the C++ URCU_FORCE_CAST macro (used by rcu_dereference) omits 'typename' in a dependent context. Backport the one-line upstream 0.15 fix as a header-only patch. C++-only, no ABI/soname/runtime impact. Signed-off-by: Ankita Pareek <ankitapareek@microsoft.com>
The previous patch used spaces instead of the tab present in the released tarball's compiler.h, so %autosetup (patch --fuzz=0) rejected the hunk. Regenerate the patch from the source-server tarball to match context exactly. Signed-off-by: Ankita Pareek <ankitapareek@microsoft.com>
