The end goal of this exercise is to remove all mutable global state so
that multiple Blueprint instances can be run in the same process.
This is done by plumbing the necessary data through the configuration.

ShellEscape(string) doesn't escape a string with spaces like "arg1
arg2". However, when we want to escape a string to use it as an
argument, then strings with spaces should be escaped.
For example,
"command " + ShellEscapeIncludingSpaces("a b")
becomes "command 'a b'" so that "command" will get "a b" as a single
argument.

numericStringLess("1a", "11a") would strip the equal prefix "1" and
then compare the bytes "a" and "1", when it should have compared the
numbers 1 and 11. Fix it by handling the case where the last equal
byte was numeric and the first differing byte is numeric in one
string and non-numeric in the other.
numericStringLess("12", "101") would strip the equal prefix "1" and
then compare the numbers 2 and 01, when it should have compared the
numbers 12 and 101. Fix it by tracking the beginning of the sequence
of numeric bytes containing the differing byte.

This is so that soong_build doesn't know the current directory, thereby
avoiding one way to leak information.

The function now can traverse into a field whose type is slice of
struct. When reading field values from the returned indexes, Soong will
check if the next field is a slice of struct or not. If so, it will
recurse into all the values in the slice.

Previously, an incantation like `bpfmt -o <$BAD_BP` would print to
stderr as expected, but then it would exit with 0. This is different
than the behavior of `bpfmt -o $BAD_BP`, which correctly exits with a
non-zero status code (in addition to printing the issues to stderr).
Test: m bpfmt; out/soong/host/linux-x86/bin/bpfmt -o <$BAD_BP; echo $?

ReplaceExtension had an unexpected behaviour when the file did not have
an extension. In certain cases, the final path would be severely
trimmed: out/.intermediates/my_file would become out/.new_extension.
Explicitly handle the case by appending the new extension.

Fix detecting cycles in parallelVisit
Optimize HasTag function

Fix detecting cycles in parallelVisit when the first alphabetical
module is not part of the cycle, but depends on the cycle. Instead of
starting from the first alphabetical module, check every module in a
determinsitic order and return the first time a cycle is found.
Test: Test_parallelVisit

The commits optimizes HasTag function by avoiding
the call to strings.Split that allocates a list of strings.
HasTag is called from the ExtendProperties family of functions.
So this new implementation would benefit any primary builder
that extensively uses property appending.
Add a small benchmark for HasTag function.
It shows that HasTag is speed up by a factor of 2-3 with the new
implementation.

Optimize updateDependencies
Write build definitions directly to output writer
Memoize full names of variables, pools and rules
Optimize arg parsing in buildDef.WriteTo
Increase ninja file writer buffer
Use io.StringWriter in ninjaWriter

Avoid reallocating module.forwardDeps and module.reverseDeps every
time through updateDependencies by resetting the slices without
reducing their capacity. Accumulate dependencies to visit directly
into module.forwardDeps. Use a loop instead of a map to check
for duplicates, average number of dependencies is measured to be
9.5, although there are a few outliers with up to 2108.
Reduces mean soong_build execution time on internal master from 87s
to 82.7s (5%).

buildDef.WriteTo was calling valueList to convert all the build
parameter ninjaStrings into strings, which uses ValueWithEscaper
to build a strings.Builder. This results in building a string
only to immediately copy it into the output writer's buffer.
Instead, pass an io.StringWriter to ValueWithEscaper so it can
build the string directly into the output writer's buffer. This
requires converting ninjaWriterWithWrap into an io.StringWriter.

Variables, pools and rules each computed their full names every time
they were referenced, which required string concatenations. Since
every one is guaranteed to be accessed at least twice, once when the
definition is written into the ninja file and once for each reference,
precompute the full name. For local variables that can be done
during initialization, but for global variables add a pass to
PrepareBuildActions to compute the name for each live variable using
the final package names.

Arguments to build definitions were copied from the input map to an
map with the name and value expanded, then to a list of names for
sorting, and then written, which required iterating over a map three
times. Expand the name and value into a list of name value pairs,
and then do the rest of the operations on the list instead.
