Subject: procd: rework trigger handling
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=8891d941e054331dab027a58dd24e1aeb88acfc3;p=oweals%2Fopenwrt.git

procd: rework trigger handling

Open/close triggers array around service_triggers call to make using
multiple triggers easier to deal with.
The API was quite confusing, because some functions contained implicit
trigger open/close calls and some didn't.
