Running with the data race detector enabled hits a 8192 active

by limiting parallelVisit to 1000 goroutines. Also rewrite
cloneModule in terms of parallelVisit.

Patch and PatchList provide an API for making changes to substrings
of a Blueprint file by parsing the AST and using the token positions
to perform text replacements.
Test: modify_test.go
Change-Id: Ibb8993221982b54602ba5a05486198fab8d35a67
End() was previously only used to determine if a comment was within
a Node, so it used the expedient definition of the position of the
last token in the node. In the next patch it will be used for
capturing substrings of the Blueprint file, so make it point to
the character after the last token instead.
Also add tests for it.

When passing "-c" to the Go compiler, any time this value changes, we'd
force all of the Go compiles to rebuild. This could trigger a
substantial portion of the tree to rebuild (anything that transitive
depends on a Go helper tool).
We're running into issues when moving output directories between
multiple GCE machines with different core counts, but are otherwise
identical. This could also hit users moving/mounting disks between
machines, though changes to other host tools can make an impact too.
On my 48-core machine, I get a ~15% benefit from going from -c 1 to -c
48, but also ~12% benefit from going from -c 1 to -c 8. So this will
still let us scale somewhat, but prevent rebuilds when transitioning
between machines that are more likely building Android.
In Go 1.10, runtime.GOROOT() will attempt to find the current location
of the go binaries, instead of using the GOROOT_FINAL that was baked
into the binaries. This means that GOROOT() will usually return an
absolute path.
We avoid putting absolute paths into the ninja file, since any change to
the paths would then cause all of the actions including it to rebuild.
Since we've got a decent number of build tools in Android using Go now,
this causes us to rebuild a decent portion of the tree.
Instead of passing the GOROOT around manually in a side channel, just
let the Go 1.10 detection do its thing, and always try to turn the
result into a relative path.
This makes it easy for users of Glob to detect whether the match is a
file or directory. Doing the check at this level means that the filelist
file used as a dependency will be updated if a directory is replaced
with a file of the same name, or vice versa.

Performing the same glob twice, once with excludes=nil and once
with excludes=[]string{} would hit the same entry in the glob
cache (since the glob filename would be the same), but fail
the verifyGlob check because DeepEqual considers []string(nil)
and []string{} to be different. Use a manual array check
instead.

Move the docs to the main stage and make a phony rule to build
them. This will allow the primaray builder to choose not to

Glob names were appending every excluded file, which could result
in too many / characters for ninja to handle. Use a hash if the
result contains too many / characters.

PreSingletons use the same interface as Singletons, but run after
parsing all the blueprint files but before running any mutators
or GenerateBuildActions. They can be used to perform global setup,
including generating rules, that may be referenced by later
mutator or generate passes.

Support int64 number instead of int to be more fixed to bit size so
that the underlying arch won't affect overflow cases. Besides,
refection: func (v Value) Int() int64 always cast to int64 no matter the
input is int, int16, int32. Currently we always treat "-" as negative
sign to bind to next value, and "+" as plus operator to add operands
together.
So we allow:
a = 5 + -4 + 5 or a = -4 + 5
But we don't allow:
a = +5 + 4 + -4 since we don't treat "+" as a positive sign, otherwise,
a = 5 + +5 would exist which looks pretty weird. In the future, we may
want fully support number calculator logic eg, "+"/"-" can be
positive/negative sign or operator, and "(" and ")" will be considered
to group expressions with a higher precedence.
int & uint properties within struct keeps unchanged, which is only
allowed when tagged with 'blueprint:mutated'. We only allow *int64
property instead of int64 property within struct since it does't make
sense to do prepending or appending to int64.
