Botond Dénes a0c5dee2aa utils/logalloc: introduce logalloc::bad_alloc ...

This new exception type inherits from std::bad_alloc and allows logalloc
code to add additional information about why the allocation failed. We
currently have 3 different throw sites for std::bad_alloc in logalloc.cc
and when investigating a coredump produced by --abort-on-lsa-bad-alloc,
it is impossible to determine, which throw-site activated last,
triggering the abort.
This patch fixes that by disambiguating the throw-sites and including it
in the error message printed, right before abort.
