Deduplicate macros, Fix memleak in PHP < 5.4

[ghost]

See #802, #910, #914

Bonus: free all allocated memory on fatal error without segmentation faults (should we backport this to 1.2.1?)

[phalcon]

This can't be merged, could you please rebase it?

[ghost]

Rebased against current HEAD

Build for 5.3.3 failed due to Travis error:

Cloning into 'php-tests/library/Mustache'...
fatal: Could not read from remote repository.

[phalcon]

@niden merged 1.3.0 into master, so I expect developers install from master, no?

[ghost]

I have a branch, 1.2.1-sj with all bug fixes since 1.2.1 (only bug fixes, no new functionality). We can merge it as 1.2.2 if you want once all Travis tests pass.

[niden]

Vladimir, please merge into 1.3.0 which right now is in sync with master.

Thanks!

OK, I want to try to fix #911 first.

1.3.0 is c307a28
master is 892bc34
1.2.1 is e2fa114

Am I missing something?
