e271b17 Remove the string optimization since it causes no real performance gain but increases generation time of the dumped PHP Container
Discussion
----------
PhpDumper and large strings
When the PhpDumper is dealing with longer strings, the regular expression performed to optimize this can be quite a performance hog.
In our case sometimes the dumper takes more then 30 seconds if leaving this enabled. Disabling it will bring it back to sub-second speed.
This patch makes the optimization optional by passing in an additional container option.

I don't like adding yet another option for something that should "just works". It would be better to find a better way to optimise the strings for all cases.

I never really tested how much of a runtime difference it incurs when either using the "optimized" version or the non optimized version, so:
Having an example at hand which generates stable results yields (in a non-debug environment with a booted container using either of the optimization methods):
Without optimized strings:

```
So the response times differ by around 0.8ms
Building the non-optimized container takes around 800ms
Building the optimized container takes 43 seconds
From my Point of View it would just be viable to remove the optimization (since it already incurred some issues fixed in 808088a3ca).
I do not see a way how to improve the regexps (but by all means I'm no regular expression guru)

I'm also for removing these optimizations. What others think?

I'm +1 for removing this feature.
The performance boost is to small.

c195957 [Components] Tests/Autoloading fixes
Discussion
----------
Fix components
See #4141
----
This PR:
* configures each component to use composer to manage "dev" dependencies instead of env variables;
* adds phpunit configuration file on Filesystem component;
* fixes READMEs.
It's mergeable without any problems, but I would recommend to wait a fix in Composer in order to use `self.version` in `require`/`require-dev` sections.
Note: I kept `suggest` sections because it makes sense but this PR doesn't aim to provide useful explanations for each entry. It could be another PR, not that one.

@fabpot I reviewed each component, one by one. Now `phpunit` always works, even if tests are skipped. A simple `composer install --dev` allows to run the complete test suite. Each commit is well separated from the others. I guess, everything is ok now.

Please squash, as it makes no sense to have the same commit for each component.

Can you squash your commits before I merge? Thanks.

It does not seem that the commits are squashed.
