Make mysql5 and mysql5-devel as similar as possible

[ryandesign@…]

The mysql5 and mysql5-devel portfiles currently differ in a number of ways:

1. The whitespace differs. Fix this so that it's easy to see at a glance how mysql5 and mysql5-devel differ functionally.
2. mysql5-devel installs to different directories than mysql5. Fix this so that ports that depend on mysql5 would also work if mysql5-devel were installed instead.
3. Possibly more?

jwa, the other maintainer of mysql5-devel, agrees with these changes.

• r33655: whitespace and formatting changes only

• r33697: Changed mysql5-devel to install into the same locations as mysql5. Note that it already installed some files to the same locations before, such that it was never possible to install mysql5 and mysql5-devel at the same time:

$ sudo port install mysql5-devel

This change will therefore just make it easier for other software to link with either mysql5 or mysql5-devel, whichever one the user may have installed.

The mysql5 portfile uses --with-federated-storage-engine (added in #12604) and I thought I needed to add that to mysql5-devel (and did, in r33698). But it turns out MySQL 5.1 enables the federated storage engine not with that switch, but with the --with-plugins switch, and mysql5-devel already has --with-plugins=all (so I reverted my change in r33699).

• r33700: make the master_sites sections more similar by computing and using a variable for the branch version rather than repeating the number in each URL.

[ryandesign@…]

mysql5-devel uses --without-server; this will be added to the next version of mysql5 via #14146.
