* Remove needless RegExp flag
In fixed case, `/g` flag is needless in the boolean context.
* Remove needless RegExp capturing
Use non-capturing grouping or remove capturing completely when:
* capturing is useless per se, e.g. in test() check;
* captured groups are not used afterward at all;
* some of the later captured groups are not used afterward.
* Use test, not match/exec in boolean context
match() and exec() return a complicated object,
unneeded in a boolean context.
* Do not needlessly repeat RegExp creation
This commit takes RegExp creation out of cycles and other repetitions.
As long as the RegExp does not use /g flag and match indices,
we are safe here.
In tests, this fix hardly gives a significant performance gain,
but it increases clarity and maintainability,
reassuring some RegExps to be identical.
RegExp in functions are not taken out of their functions:
while these functions are called many times
and their RegExps are recreated with each call,
the performance gain in test cases
does not seem to be worth decreasing function self-dependency.

Use assert.strictEqual instead of assert.equal in tests, manually
convert types where necessary.

Updating tests to use `common.fixturesDir` whenever possible/reasonable.
Left out things like tests for `path` and `require.resolve`.

In several places throughout the code we write directly to stderr
to report warnings (deprecation, possible eventemitter memory leak).
The current design of simply dumping the text to stderr is less
than ideal. This PR introduces a new "process warnings" mechanism
that emits 'warning' events on the global process object. These are
invoked with a `warning` argument whose value is an Error object.
By default, these warnings will be printed to stderr. This can be
suppressed using the `--no-warnings` and `--no-deprecation` command
line flags. For warnings, the 'warning' event will still be emitted
by the process, allowing applications to handle the warnings in custom
ways. The existing `--no-deprecation` flag will continue to supress
all deprecation output generated by the core lib.
The `--trace-warnings` command line flag will tell Node.js to print
the full stack trace of warnings as part of the default handling.
The existing `--no-deprecation`, `--throw-deprecation` and
`--trace-deprecation` flags continue to work as they currently do,
but the exact output of the warning message is modified to occur
on process.nextTick().
The stack trace for the warnings and deprecations preserve and point
to the correct call site.
A new `process.emitWarning()` API is provided to permit userland
to emit warnings and deprecations using the same consistent
mechanism.
Test cases and documentation are included.
