Mårten Kongstad d7e8a534d0 idmap2: add debug information to idmap file format
Add a new variable length string to the idmap file format. This string will
hold debug information like fulfilled policies and any warnings triggered while
generating the file.

Bump the idmap version to 3.

Adjust the idmap header definition in ResourceType.h to take the new string
into account.

Example debug info:

  $ idmap2 create \
        --target-apk-path frameworks/base/cmds/idmap2/tests/data/target/target.apk \
        --overlay-apk-path frameworks/base/cmds/idmap2/tests/data/overlay/overlay.apk \
        --idmap-path /tmp/a.idmap \
        --policy public \
        --policy oem

  $ idmap2 dump --idmap-path /tmp/a.idmap
  target apk path  : frameworks/base/cmds/idmap2/tests/data/target/target.apk
  overlay apk path : frameworks/base/cmds/idmap2/tests/data/overlay/overlay.apk
  I fulfilled_policies=oem|public enforce_overlayable=true
  W failed to find resource "integer/not_in_target" in target resources
  0x7f010000 -> 0x7f010000 integer/int1
  0x7f02000c -> 0x7f020000 string/str1
  [...]

  $ idmap2 dump --idmap-path /tmp/a.idmap --verbose

  [...]

Also, tell cpplint to accept non-const references as function parameters:
they make more sense as out-parameters than pointers that are assumed to
be non-null.

Also, switch to regular expressions in the RawPrintVisitorTests: no more
manual fixups of the stream offsets! Tell cpplint that the <regex>
header is OK to use.
