Merge branch '1.x'

Make help output help2man-friendly

These changes follow regular advices for CLI output and allow help2man
to produce a meaningful manpage out of it.

Set correct number of s/r conflicts

Move parser to Parser\Php5

Old name still exists.

Anonymize some callbacks

Drop short array simulation from .phpy syntax

Instead use real short array syntax.

Drop support for PHP 7 aliases

Drop support for legacy aliases from v0.9

Drop support for old Node format

Drop 5.4 support from emulative lexer

Set version to 2.0-dev. Drop PHP 5.3 support

Update documentation link

Release PHP-Parser 1.3.0

Try .17G print if .16G is not enough

This should be enough for all cases, because: A double has 53 bits
of mantissa (including the implicit 1 bit), which is 53*ln(2)/ln(10)
= 15.95 d

Try .17G print if .16G is not enough

This should be enough for all cases, because: A double has 53 bits
of mantissa (including the implicit 1 bit), which is 53*ln(2)/ln(10)
= 15.95 decimal digits. However the leading decimal digit may encode
less than the usual 3.32 bits, which will push this over the edge to
requiring 17 decimal digits.

Add some more tests

Drop Lexer::getPosition()

This was a leftover from the original column info implementation.

Update changelog, fix typos

Increase float pretty printing precision

This removes the reliance on the "precision" ini setting.
Furthermore the default of precision=14 is not sufficient.

Add some error documentation

Drop name magic from rebuildParser.php

Now using explicitly imported names, instead of magically
prepending Name\.

Also remove trailing whitespace from generated file.

Add some recovery tests

Don't distinguish test-fail / test

With error recovery this is fluid. Using .test for everything.

Enable basic error recovery

Adding only a single recovery rule for now.

The API is now:
* throwOnError parser option must be disabled.
* List of Errors is available throug

Enable basic error recovery

Adding only a single recovery rule for now.

The API is now:
* throwOnError parser option must be disabled.
* List of Errors is available through $parser->getErrors(). This
method is available either way.
* If no recovery is possible $parser->parse() will return null.
(Obviously only if throwOnError is disabled).
