Greetings,
The following webrev contains fixes for the following issues:
15386 action fromstr could pool attribute names to reduce memory usage
15388 actions could use __slots__ to reduce memory usage
15389 pkgplans could use __slots__ to reduce memory usage
webrev:

These changes build onto those done for bugs 15169, 15176, and 15211.
Test results below are a comparison based on a workspace with changes
for those bugs.
The x64 desktop system referenced below is an Intel Core 2 DUO E8400 w/
8GiB ram and 10K RPM SATA drive running OpenSolaris b135.
The x64 laptop system referenced below is a laptop w/ an Intel Core 2
DUO T9600 w/ 4GiB ram and a 4200 RPM SATA drive running OpenSolaris b131.
The T5120 system referenced below is a SPARC T5120 w/ 16GB memory.
Operation Memory Usage Comparisons (before -> after)
====================================================
Peak memory usage based on the first column of pmap -x total output.
$ pfexec pkg -R / install --no-refresh --no-index -n redistributable
x64 desktop: 467,420KiB -> 380,224KiB
x64 laptop: 534,360KiB -> 453,492KiB
$ pfexec pkg -R / image-update --no-refresh -n (b131 -> b135)
x64 laptop: 587,448KiB -> 473,100KiB
$ pkg -R /tmp/empty_user_image install --no-refresh -n slim_install
x64 desktop: 445,344KiB -> 420,064KiB
$ pkg -R /tmp/empty_user_image install --no-refresh -n system/manual
x64 desktop: 169,880KiB -> 169,827KiB
Operation Timing Comparisons (before -> after)
==============================================
Timings are approximations of the best of three executions.
