BUG:187441275
Problem:
ueventd: coldboot took too much time
Solution:
1.The parallel restorecon dirs can be configured in ueventd.rc
2.Add 'parallel_restorecon_dir' keywords
parallel_restorecon_dir <directory>
Verify:

ueventd.rc scripts belong in the /etc/ directory of their given
partition, not the root of the partition. This can cause problems,
especially since Android.bp cannot write to the root directly, forcing
vendors to use Android.mk for these files. Note that
/system/etc/ueventd.rc moved long ago.

Vendors have an interest in importing ueventd files based on certain
property values. Instead of baking this logic in the ueventd binary,
add the import option from the init parser to the ueventd parser, to
allow vendors to expand as needed.
Test: imported files are parsed

Userspace may want to load a different firmware than the one that the
kernel requests in some cases, therefore this change adds the ability
to ueventd to run an external handler that will determine the name of
the file that should actually be loaded.

5aa6197d5f added the ability to
parallelize restorecon to speed up boot for devices that have not
completely moved to genfscon. This parallel restorecon happens after
the parallel ueventd handling.
This causes a performance regression for devices that have moved to
genfscon, since previously, the restorecon() was done in the main
ueventd thread in parallel with the uevent handlers.
I also tried to run the fully parallelized restorecon in parallel with
the uevent handlers, but that did not make any change to the cold boot
time, likely due to the additional overhead of parallelizing the work.

Test: blueline coldboot time returns to pre-regression time.

Some configurations won't allow ueventd to have CAP_NET_ADMIN, so the
new default size of 16M is not possible for those. Those
configurations also won't need such a large buffer size, so this
change allows devices to customize the SO_RCVBUF(FORCE) size for the
uevent socket.
This is done by adding the line 'uevent_socket_rcvbuf_size <size>' to
your device's ueventd.rc file. <size> is specified as a byte count,
for example '16M' is 16MiB.
The last parsed uevent_socket_rcvbuf_size line is the one that is
used.

Some devices have modules.alias and modules.dep for modprobe and other
purposes but do not want to opt into ueventd auto loading their
modules. Therefore we add a flag that can be added to ueventd
configuration files to opt into this behavior.

Test: check that modules are loaded with this opt-in

Since some vendors will have firmware in mount points in
/mnt/vendor/..., we extend the ueventd script language to allow
specifying the firmware directories.
Also, move the existing 4 directories to ueventd.rc as a primary user
of this mechanism.

print the error pointing to the line where the section starts.

* Remove the Parser singleton (Hooray!)
* Rename parser.* to tokenizer.* as this is actually a tokenizer
* Rename init_parser.* to parser.* as this is a generic parser
* Move contents of init_parser_test.cpp to service_test.cpp as this
actually is a test of the parsing in MakeExecOneshotService() and
nothing related to (init_)parser.cpp

devices.cpp handles too many things for creating one class. This
change breaks it up into various files and classes.
* Parsing is moved to ueventd_parser.cpp
* Reading from the uevent socket and Cold booting is moved to a
UeventListener class, in uevent_listener.cpp
* Firmware handling is moved to firmware_handler.cpp
* The remaining contents form a DeviceHandler class within devices.cpp

Previously init_parser.cpp was made generic and capable of parsing any
number of differently named 'sections' or prefixed lines. We now use
these capabilities to do the parsing for ueventd.

By default ueventd creates device nodes under /dev based on the ueventd
DEVPATH. Several subsystems have special rules which are hardcoded in
devices.c. Moving forward these special rules should go in ueventd.rc.
Special rules have the syntax:
subsystem <s>
devname (uevent_devname|uevent_devpath)
[dirname <dir>]
Devices matching SUBSYSTEM=<s> will be populated under <dir>. dirname
is optional and defaults to /dev. If dirname is provided, <dir> must
start with "/".
If devname is uevent_devname, ueventd will create the device node as
<dir>/DEVNAME. DEVNAME may include intermediate subdirectories, which
ueventd will automatically create.
If devname is uevent_devpath, ueventd will use the legacy behavior of
computing DEVPATH_BASE=basepath(DEVPATH), and creating the device node
as <dir>/DEVPATH_BASE.
The new parsing code is based on init_parser.c, with small tweaks to
handle commands which don't fall under a section header.

This should be much nicer than peppering init.rc with chown/chmod
directives.
Also, remove some dead code and obsolete comments.
