v1.0.0: Updated README and CHANGELOG

Released on: Nov 7, 2019

• parray:
  • New data storage behind parray objects
  • New functions for set management: parray_union(), parray_diff(),
    parray_sort(), parray_concat(), providing equivalence to their
    plist counterparts
  • Changed signatures for parray iter functions
• plist:
  • Improvements of the plist data type so that plistel provides no
    (error-prone!) back-pointer to its list anymore.
  • Speed optimization on plist_diff() and plist_union().
  • New flag PLIST_MOD_KEEPKEYS to keep key order and implement opposite hiding (last key collision will be chained to the end).
  • New function plist_getkey() to iterate over available keys in a
    hash-table configured plist object.
  • Flags generally stored as short values rather than int.
• pccl:
  • Changed underlying data structures to the much faster parray.
• utf8:
  • putf8_strlen() improved
• other:
  • Switched license terms from 3-clause BSD to MIT
  • Entirely restructured src/-folder.
  • Modularization of the command-line tools pdoc, pinclude and pproto.
  • Began development of a ptest utility to perform automated tests and CI, implemented several tests cases in different modules.
  • Improved program tracing facilities, including clock measuring to indicate slow running functions.
  • Improved documentation and README.md.
  • Shell script standalone.sh to build stand-alone source versions of
    libphorward to be copied into other projects.
  • Moved the pany dynamic variant data type away into the phosphor repository.
