Tom Cherry fa0c21c94c init: Create classes for Action and Command
This creates the concept of 'event_trigger' vs 'property_trigger'

Previously these were merged into one, such that 'on property:a=b &&
property:b=c' is triggered when properties a=b and b=c as expected,
however combinations such as 'on early-boot && boot' would trigger
during both early-boot and boot.  Similarly, 'on early-boot &&
property:a=b' would trigger on both early-boot and again when property
a equals b.

The event trigger distinction ensures that the first example fails to
parse and the second example only triggers on early-boot if
property a equals b.

This coalesces Actions with the same triggers into a single Action object

Yusuke Sato f93d42933b Stop calling fsck on shutdown by default
Instead, run the command only when sys.powerctl is set to
"shutdown,userrequested". This way, we can avoid running
fsck when shutdown is triggered due to a low power state.

This is a follow-up CL for http://r.android.com/158525.

Yusuke Sato 0df08271fb Use fsck.f2fs -a instead of -f for faster boot
and run fsck with -f on clean shutdown instead.

With -f, fsck.f2fs always performs a full scan of the /data
partition regardless of whether the partition is clean or not.
The full scan takes more than 2 seconds on volantis-userdebug
and delays the OS boot.

With -a, the command does almost nothing when the partition
is clean and finishes within 20-30ms on volantis-userdebug.
When the partition has an error or its check point has
CP_FSCK_FLAG (aka "need_fsck"), the command does exactly the
same full scan as -f to fix it.

Tom Cherry eaa3b4ec6f Fix insmod module size
read_file() used to append a new line character to the end of the buffer it
returns, because parse_config() isn't able to cope with input that's not
'\n'-terminated. Fix read_file() to be less insane, and push the workarounds
into the parse_config() callers.

Longer term we should rewrite parse_config().

any issues when running in block encrypted mode, as well as speeding

Johan Redestig 7e952f41f1 Bump do_write buffer size
In the case of do_write (write to generic file) there
is really no relation to the PROP_VALUE_MAX limitation
of system properties. The current value, 92, is not so
much for writing to files so bump it a bit.

Ideally there should not be any low hard limit in this
case. Either expand_props should allocate the output
buffer or take the output fd and to streaming write.
Such a change is rather invasive though and at this
point in time it seems reasonable that one dont want
more than 256 character strings in the init files.

This isn't particularly useful in and of itself, but it does introduce the

about how to debug init crashes), and made me aware of how unpleasant the
existing parser is.

I also fixed a bug in passing --- unless you thought the "peboot" and "pm"
commands were features...
