libphobos: Merge common version blocks using arch_any conditions · 15684250

This sets a precedence in upstream for merging architecture agnostic
C bindings into one block, rather than separate duplicated blocks.

A nice side-effect is it almost completes the C bindings for
s390-linux-gnu and sparc-linux-gnu, and fixes a bug on MIPS32 where
O_SYNC had the wrong value.

Backported from upstream druntime master.

The class API provides no way to modify the members, so we can share

Also adjust the what() string to allow distinguishing between an empty

[libbacktrace] Fix segfault upon allocation failure · 18c742b5

If the allocation of abbrevs->abbrevs in read_abbrevs fails, then
abbrevs->num_abbrevs remains nonzero, and consequently free_abbrevs will
segfault when accessing abbrevs->abbrevs.

Fix this by setting abbrevs->num_abbrevs only after abbrevs->abbrevs
allocation has succeeded.

Bootstrapped and reg-tested on x86_64.
