contrib/pgcrypto should also be built as a shared module (same as adminpack)

Log message:
Changes 8.4.3:
* Add new configuration parameter ssl_renegotiation_limit to control
  how often we do session key renegotiation for an SSL connection
* Fix possible deadlock during backend startup
* Fix possible crashes due to not handling errors during relcache
  reload cleanly
* Fix possible crash due to use of dangling pointer to a cached plan
* Fix possible crash due to overenthusiastic invalidation of cached
  plan for "ROLLBACK"
* Fix possible crashes when trying to recover from a failure in
  subtransaction start
* Fix server memory leak associated with use of savepoints and a
  client encoding different from server's encoding
* Fix incorrect WAL data emitted during end-of-recovery cleanup of a
  GIST index page split
* Fix bug in WAL redo cleanup method for GIN indexes
* Fix incorrect comparison of scan key in GIN index search
* Make substring() for bit types treat any negative length as meaning
  "all the rest of the string"
  The previous coding treated only -1 that way, and would produce an
  invalid result value for other negative values, possibly leading to
  a crash (CVE-2010-0442).
* Fix integer-to-bit-string conversions to handle the first
  fractional byte correctly when the output bit width is wider than
  the given integer by something other than a multiple of 8 bits
* Fix some cases of pathologically slow regular expression matching
* Fix bug occurring when trying to inline a SQL function that returns
  a set of a composite type that contains dropped columns
* Fix bug with trying to update a field of an element of a
  composite-type array column
* Avoid failure when "EXPLAIN" has to print a FieldStore or
  assignment ArrayRef expression
  These cases can arise now that "EXPLAIN VERBOSE" tries to print
  plan node target lists.
* Avoid an unnecessary coercion failure in some cases where an
  undecorated literal string appears in a subquery within
  "UNION"/"INTERSECT"/"EXCEPT"
  This fixes a regression for some cases that worked before 8.4.
* Avoid undesirable rowtype compatibility check failures in some
  cases where a whole-row Var has a rowtype that contains dropped
  columns
* Fix the STOP WAL LOCATION entry in backup history files to report
  the next WAL segment's name when the end location is exactly at a
  segment boundary
* Always pass the catalog ID to an option validator function
  specified in "CREATE FOREIGN DATA WRAPPER"
* Fix some more cases of temporary-file leakage
* Add support for doing FULL JOIN ON FALSE
* Improve constraint exclusion processing of boolean-variable cases,
  in particular make it possible to exclude a partition that has a
  "bool_column = false" constraint
* Prevent treating an INOUT cast as representing binary compatibility
* Include column name in the message when warning about inability to
  grant or revoke column-level privileges
  This is more useful than before and helps to prevent confusion when
  a "REVOKE" generates multiple messages, which formerly appeared to
  be duplicates.
* When reading "pg_hba.conf" and related files, do not treat
  @something as a file inclusion request if the @ appears inside
  quote marks; also, never treat @ by itself as a file inclusion
  request
* Prevent infinite loop on some platforms if a directory is named as
  an inclusion target in "pg_hba.conf" and related files
* Fix possible infinite loop if SSL_read or SSL_write fails without
  setting errno
  This is reportedly possible with some Windows versions of openssl.
* Disallow GSSAPI authentication on local connections, since it
  requires a hostname to function correctly
* Protect ecpg against applications freeing strings unexpectedly
* Make ecpg report the proper SQLSTATE if the connection disappears
* Fix translation of cell contents in psql \d output
* Fix psql's numericlocale option to not format strings it shouldn't
  in latex and troff output formats
* Fix a small per-query memory leak in psql
* Make psql return the correct exit status (3) when ON_ERROR_STOP and
  --single-transaction are both specified and an error occurs during
  the implied "COMMIT"
* Fix pg_dump's output of permissions for foreign servers
* Fix possible crash in parallel pg_restore due to out-of-range
  dependency IDs
* Fix plpgsql failure in one case where a composite column is set to NULL
* Fix possible failure when calling PL/Perl functions from PL/PerlU
  or vice versa
* Add volatile markings in PL/Python to avoid possible
  compiler-specific misbehavior
* Ensure PL/Tcl initializes the Tcl interpreter fully
  The only known symptom of this oversight is that the Tcl clock
  command misbehaves if using Tcl 8.5 or later.
* Prevent ExecutorEnd from being run on portals created within a
  failed transaction or subtransaction
  This is known to cause issues when using "contrib/auto_explain".
* Prevent crash in "contrib/dblink" when too many key columns are
  specified to a dblink_build_sql_* function
* Allow zero-dimensional arrays in "contrib/ltree" operations
* Fix assorted crashes in "contrib/xml2" caused by sloppy memory
  management
* Make building of "contrib/xml2" more robust on Windows
* Fix race condition in Windows signal handling
  One known symptom of this bug is that rows in pg_listener could be
  dropped under heavy load.
* Make the configure script report failure if the C compiler does not
  provide a working 64-bit integer datatype
  This case has been broken for some time, and no longer seems worth
  supporting, so just reject it at configure time instead.
* Update time zone data files to tzdata release 2010e for DST law
  changes in Bangladesh, Chile, Fiji, Mexico, Paraguay, Samoa.
