PRoot v5.1.0

[Cédric VINCENT]

Hi all,

We are pleased to announce PRoot v5.1.0.  In a couple of words, this
release fixes some critical regressions that were introduced in the
v5.0.0 release.  This is also the first release that preserves the
name of prooted programs.

New features
------------

+ Processes under PRoot now appear with their real names, that is,
  they are not renamed "ld-linux.so" or "prooted-..." anymore:

  before:

      $ proot-v4.0.3 ps
        PID TTY          TIME CMD
       7885 pts/11   00:00:00 bash
       8131 pts/11   00:00:00 proot-v4.0.3
       8132 pts/11   00:00:00 ld-2.17.so

      $ proot-v5.0.0 ps
        PID TTY          TIME CMD
       7885 pts/11   00:00:00 bash
       7916 pts/11   00:00:00 proot-v5.0.0
       7917 pts/11   00:00:00 prooted-7916-Jb

  now:

      $ proot-v5.1.0 ps
        PID TTY          TIME CMD
       7885 pts/11   00:00:00 bash
       8585 pts/11   00:00:00 proot-v5.1.0
       8586 pts/11   00:00:00 ps

Fixes
-----

+ It is now possible to use GDB against multi-threaded programs under
  PRoot x86_64 and x86.

+ It is possible to execute x86_64 programs from x86 programs again.

+ It is possible to use x86 ptrace-based programs (strace, gdb, ...)
  under PRoot x86_64 again.

+ The loader is now built with the "build-id" linker option explicitly
  disabled.  This special section might interfere with loaded
  programs.

+ The loader can now load relocatable objects that have a predefined
  base address.
