The port to use should be 2152, not 2153.

We want the log in case of failure also for the case:
    if (nCCE + (1<<dci_alloc->L) > nCCE_max)

We have to not only ensure that the CCE is free but
also that it's below the number of availables CCEs
with respect to the current PDCCH size.

Summary of changes:
- bug fixes
  * UE TDD fixes
  * PDCCH size computation (at phy level, still to be corrected at mac level)
  * DAI increment
  * fix run_enb_ue_virt_noS1 and run_enb_ue_virt_s1 to use Rel14 and
     have --xforms to work
  * compilation warning removals
  * better oaisim logging (print UE security keys,
    print version (git commit ID) at runtime, print working directory)

See merge request !190

Problems reported by Jorge Muñoz Castañer <jorgem@gti.uvigo.es>.

- use Rel14 binaries (those are produced by default)
- let -x option work to have graphical output
- fix VCD missing 'echo'

we can compute CCE_max_used_index out of the loop.

get_nCCE returns the number of available CCEs.

We can put the CCEs numbers [ 0 .. get_nCCE-1 ],
so we need to use <, not <=.
