Add /var/tmp/* to mtree.prebuildexclude and mtree.preinstexclude.
A few tex ports put their temporary file in /var/tmp/texfonts, some other ports put temporary files in /var/tmp/vi.recover.
Only need to load cache if tracking buildtimes

MFH
Add hash_get,set,unset which allows setting aribtrary variables like a hash-table

Note that sh(1) does implement variables in hash tables, so this
should be fast
priorities: Use a hashtable instead of executing awk(1) in every balance_pool iteration
Allow boosting priorities based on pkgname globbing
balance_pool: Fix race between checking for empty dir and grabbing lock

MFH
Just create unbalanced dir with others
Add missing eargs function names
Fix testport: Need to handle packages not in pkg_deps
testport: Fix check_moved warning when tested port has no deps

MFH
Update todo
bulk: Add -k to set PORTTESTING_FATAL=no
bulk -at: Automatically set PORTTESTING_FATAL=no
poudriere.8: Note that -r is also implied by -at
list_deps: Fix to actually remove duplicates and also remove blank lines

MFH
No longer need to remove extra spaces, list_deps() won't have blanks now

MFH
check_leftovers: Show modified output

nmtree:
  ====>> Files or directories modified:
  @dirrm %%DOCSDIR%% gid (82, 0)
  @dirrm /var/qmail gid (82, 0)
nmtree:
  ====>> Files or directories modified:
  @dirrm %%DOCSDIR%% gid expected 82 found 0
  @dirrm /var/qmail gid expected 82 found 0

MFH
Make testing errors and build failure more clear
buildlog_stop: Don't return 1 if the port was successful
Fix regression from -cat -k, don't warn on -a
