value.Type and value.Pos changed to methods, change the users that were
not caught by error checking to use Type() or Pos().

There may be multiple skipped comments in a row, convert
p.skippedComments to a list and add a test.
Change-Id: I30dcff269bee56fd51ef9513dab7c7885c44b7d7
Determining which comments are contiguous is difficult once they have
been parsed into an out-of-band comment list, as any intervening nodes
are in a separate structure. Group the comments into CommentGroups
during the parsing stage instead.

Pos is going to be part of the Node interface, rename the Pos member
of structs to be more specific.

It wasn't adding anything useful, and it resulted in Name.Name to get to
the identifier. Replace Name Ident with Name string; NamePos
scanner.Position.

Refactor the blueprint parser Value object, which contained a Type enum
and members to hold every possible type, into an interface (now called
Expression). Rename the existing Expression object that represented a binary
operator Operator.
Also adds and fixes some new printer test cases with mulitline expressions.

The Go race detector found a race condition in the parser, which
highlighted a few related bugs. A variable could be defined but
not referenced in a Blueprints file, then appended to in multiple
subdirs= Blueprints files. The race detector caught the multiple
writes to assignment.Referenced from the parsers for the subdirs
Blueprints files, but multiple appends would be much more serious.
To fix this, keep local and inherited variables separate in the
Scope object and export that info to the parser. Disallow
appending to non-local variables, which was already the intended
behavior. Only update the referenced boolean for local variables.
Together, this should prevent all writes to Assignment objects
from parsers other than the one that created them.
Also improves the error handling code and some error messages.

Refactor parsing Blueprints and walking the Blueprints tree to
allow reuse for tasks that don't involve creating moduleInfo
structures.

Add String() to print out the Comment, Text() to print out the
Comment while stripping /*, //, and */, and EndLine() to return
the line number of the last line of the comment.

Running bpfmt or bpmodify on a Blueprints file that references
variables defined in a parent Blueprints file causes parse errors
on unknown variables. Modify the parser to parse in two modes,
parser.Parse and parser.ParseAndEval. The first parses without
attempting to evaluate variables and expressions, the second
performs a full evaluation.

Trying to handle all the whitespace and newline printing inside
printToken got overly complicated, and resulted in a few bugs in
the layout around comments and indentation that were hard to fix.
Rewrite the whitespace and newline handling to be handled directly
by the object printers, using requestSpace() to ensure whitespace
is inserted and requestNewline() to ensure a newline is inserted.
Also fixes unnecessarily left aligning all comments that contain
indentation, and fixes accidentally unindenting comments that are
the last token in their indented block.

Switch back to:
moduleType {
name: value,
arch: {
x86: {
name: value,
},
},
}
This provides better consistency between properties defined at the
top level of a module and properties defined inside a map.
The parser will continue to support the other format for now, but the
printer will only produce the original format.
Add support for + operator on maps. The semantics are that keys that
exist in both maps are added with the + operator, and keys that exist
in one map are copied to the resulting map.

Support += assignments to variables. Variables are now mutable
up until they are referenced, then they become immutable. This
will allow variables to be modified in a conditional, or allow
better commenting on why parts of a variable are set.

The printer was allowing extra newlines in odd places, for example
between a property name and the '=' in a module definition. Make
newline location stricter by explicitly allowing newlines or
line comments.
Make integrating with go tools easier by putting the blueprint package
files in the top level directory of the git project instead of in a
subdirectory called blueprint.
