bash/bash-4.2-coverity.patch
Siteshwar Vashisht 91692f161e Rebase to bash-5.0
- Remove 'bash-2.02-security.patch' patch as it does not seem to be
needed.
- Remove 'bash-2.05b-xcc.patch' as this change is already in upstream.
- Remove 'bash-4.1-defer-sigchld-trap.patch' as this patch was doing
nothing and this bug that it tried to solve should be fixed in upstream
https://lists.gnu.org/archive/html/bug-bash/2012-03/msg00045.html
- Remove 'bash-4.4-coverity.patch' as it has been upstreamed.
- Delete several other patches that were not removed while rebasing to
bash-4.4.
