Noah Misch 3a0d473192 Use wrappers of PG_DETOAST_DATUM_PACKED() more. 
This makes almost all core code follow the policy introduced in the
previous commit.  Specific decisions:

- Text search support functions with char* and length arguments, such as
  prsstart and lexize, may receive unaligned strings.  I doubt
  maintainers of non-core text search code will notice.

- Use plain VARDATA() on values detoasted or synthesized earlier in the
  same function.  Use VARDATA_ANY() on varlenas sourced outside the
  function, even if they happen to always have four-byte headers.  As an
  exception, retain the universal practice of using VARDATA() on return
  values of SendFunctionCall().

- Retain PG_GETARG_BYTEA_P() in pageinspect.  (Page images are too large
  for a one-byte header, so this misses no optimization.)  Sites that do
  not call get_page_from_raw() typically need the four-byte alignment.

- For now, do not change btree_gist.  Its use of four-byte headers in
  memory is partly entangled with storage of 4-byte headers inside
  GBT_VARKEY, on disk.

- For now, do not change gtrgm_consistent() or gtrgm_distance().  They
  incorporate the varlena header into a cache, and there are multiple
  credible implementation strategies to consider.

README 

src/pl/plperl/README

PL/Perl allows you to write PostgreSQL functions and procedures in
Perl.  To include PL/Perl in the build use './configure --with-perl'.
To build from this directory use 'make all; make install'.  libperl
must have been built as a shared library, which is usually not the
case in standard installations.

Consult the PostgreSQL User's Guide and the INSTALL file in the
top-level directory of the source distribution for more information.
