Release v3.0.0

• Rewritten in C99 with 0 external dependencies.

• Significantly faster & smaller (~50KB statically compiled with musl libc, or
  even smaller than the source file with diet libc).

• Cross-compiled binaries now available thanks to
  binarybuilder.org

• Improved search path printing when libraries cannot be located.

• Improved rpath search: shows [rpath of ...] when lib is located by parent
  of parent ... of parent's rpath.

• fd inspired highlight of filename when printing paths.

• Caches files by inode instead of soname, which is useful in the sense that
  this allows you to find broken libraries that only work because of a
  particular search order of the tree. (Consider an executable A and libraries
  B, C and D, where A depends on B and C, and B and C depend on D:

    B
   / \
  A   D
   \ /
    C
  

  It may happen that D can be located through B's rpath, but not through C's.
  Then, depending on whether A - B - D is traversed first, or A - C - D, ld.so
  will complain about missing libraries or not. libtree on the other hand
  will always tell you that D can't be located through C.

• More verbosity levels -v, -vv, -vvv instead of -a and -v flags.

• Skip fewer libraries by default (only libc / libstdc++ type of libs).

• PLATFORM rpath interpolation now uses uname, this is not always the same
  as AT_PLATFORM, but unlikely to be different, and in fact the feature is
  rarely used.

• Support for NODEFLIB flag, which is a dynamic array entry flag that signals
  to the dynamic linker that it should not search default system paths
  including those specified in ld.so.conf.

• Better FreeBSD support (OSREL, OSNAME interpolation in rpaths and
  /etc/ld-elf.so.conf config file support)

• Support for relative includes in ld.so.conf config files.

Breaking changes:

• The bundling feature was dropped in 3.0.0, but is still supported in 2.x.
  It may return in a future 3.x release, but my impression is that there are
  excellent tools like Exodus which do a better job at bundling (in particular:
  they ship a copy of the dynamic linker.)
• The --skip and --platform flags were removed.
