PCRE 8.30 will break API

[Petr Pisar]

It's long time since PCRE (Perl-Compatible Regular Expression) library
has changed API or ABI. Version 8.30 is different. Besides UTF-16
support, the incompatible changes are described by upstream with these
words:

. The pcre_info() function, which has been obsolete for over 10 years,
  has been removed.

. When a compiled pattern was saved to a file and later reloaded on
  a host with different endianness, PCRE used automatically to swap the
  bytes in some of the data fields. With the advent of the 16-bit
  library, where more of this swapping is needed, it is no longer done
  automatically. Instead, the bad endianness is detected and a specific
  error is given. The user can then call a new function called
  pcre_pattern_to_host_byte_order() (or an equivalent 16-bit function)
  to do the swap.

. In UTF-8 mode, the values 0xd800 to 0xdfff are not legal Unicode code
  points and are now faulted. (They are the so-called "surrogates" that
  are reserved for coding high values in UTF-16.)

Result is pcre library has changed SONAME from libpcre.so.0 to
libpcre.so.1. Other librararies (pcrecpp, pcreposix) delivered with this
package remain compatible.

Because pcre library is part of minimal build root I choosed following
strategy to avoid breaking Koji:

(1) pcre-8.30-1 will include both new libpcre.so.1 and old libpcre.so.0.
    (This is done by copying old files from build root while building
    this new package).

(2) Reverse dependencies will be rebuilt against this new library.

(3) pcre package will be rebuilt again without the old libpcre.so.0 library.
    The usr-move of /lib*/libpcre.so* will proceede in this or another
    rebuild.
