Log message:
pbulk-base: fix double free().

Debugged by dillo & myself.

Bump version.

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.

Log message:
Use LDFLAGS, LDADD isn't in OPSYSVARS and LDFLAGS doesn't require
having to pass through MAKE_ENV.  Fixes build on SunOS.

Log message:
Use OPSYSVARS.

Log message:
pbulk-base-0.51: Extend network support for name resolution and IPv6
(where applicable).

Log message:
Revert. Committer was explicitly asked to not commit that change as it
is incompletely and incorrect.

Log message:
pbulk-base-0.51: Allow symbolic host names in distributed case.

Log message:
pbulk-base-0.50: Don't go into master mode if there is nothing to do.

Log message:
pbulk-base-0.49:
When shutting down the master after all jobs are done, send a zero
length request to the clients and wait a second for them to shutdown the
connection. Calling shutdown on the server side doesn't avoid TIME_WAIT
as originally intended.
