Log message:
*: Move SUBST_STAGE from post-patch to pre-configure

Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

Log message:
Fix typo in status message.

Log message:
Deal with stupid GCC warnings on Linux due to glibc deciding that
write's return value must be used at all times.

Log message:
pbulk-0.65: Add basic support for specifying chroot'd clients by
absolute path. Introduce hook for setting up the chroot
(client_prepare_chroot) similar to client_prepare_action for ssh
clients.

Log message:
pbulk-0.64:
Ensure to reset port after each loop, so that "client" and \ 
"client:port"
notation can be mixed.

Log message:
pbulk-0.63:
Introduce a separate client-prepare script. The default configuration
runs the renamed client_prepare_action for each scan/build client once,
dropping duplicates in the list. Clients are prepared in parallel, but
the master waits for all before starting the actual scan. Make
bulkbuild-restart re-prepare the clients, i.e. in case they have a
pkgsrc tree in a local tmpfs.

Log message:
pbulk-0.62: cleanup if either the initial pkg_add round or the package
upload failed.

Log message:
Adjust comment to reflect reality.

Log message:
pbulk-base-0.53:
After processing the tree-scan job, reassign jobs to all idle clients.
Before, this was only necessary at the very start of the build.

Log message:
pbulk-base-0.52:
Move the tree iteration logic from the master to the client. This
matters primarily when using the additional package list in the top
level makefile and ensures that the client configuration is used
consistently.
