Anna Zaks c154f7bc37 [analyzer] Add a checker that detects blocks in critical sections 
This checker should find the calls to blocking functions (for example: sleep, getc, fgets,read,recv etc.) inside a critical section. When sleep(x) is called while a mutex is held, other threads cannot lock the same mutex. This might take some time, leading to bad performance or even deadlock.

Example:

mutex_t m;

void f() {
  sleep(1000); // Error: sleep() while m is locked! [f() is called from foobar() while m is locked]
  // do some work
}

void foobar() {
  lock(m);
  f();
  unlock(m);
}

A patch by zdtorok (Zoltán Dániel Török)!
