Update libgee to 0.16.1

It seems that after the ABI break in 0.7, which probably should have
incurred a major version increment, libgee since 0.8 has been
backwardly compatible.

 * Workaround GC thread consuming 100% of CPU

Apply upstream Bug#737874 fix, remove redefinitions.
Changes 2.1.3:
* Some MUAs mangled a line in a message that begins with "From " to
  ">From " when writing to a mailbox file and feeding such an input to
  "git am" used to lose such a line.
* "git daemon" (with NO_IPV6 build configuration) used to incorrectly
  use the hostname even when gethostbyname() reported that the given
  hostname is not found.
* Newer versions of 'meld' breaks the auto-detection we use to see if
  they are new enough to support the `--output` option.
* "git pack-objects" forgot to disable the codepath to generate
  object recheability bitmap when it needs to split the resulting
  pack.
* "gitweb" used deprecated CGI::startfrom, which was removed from
  CGI.pm as of 4.04; use CGI::start_from instead.
* "git log" documentation had an example section marked up not
  quite correctly, which passed AsciiDoc but failed with
  AsciiDoctor.
Also contains some documentation updates.
Updated devel/git to 2.1.3
Import guile20-2.0.11 as lang/guile20.

GUILE, GNU's Ubiquitous Intelligent Language for Extension, is a library
that implements the Scheme language plus various convenient facilities.
It's designed so that you can link it into an application or utility to
make it extensible. Our plan is to link this library into all GNU programs
that call for extensibility.

This is guile 2.0, the current stable version.
+ guile20.
Added lang/guile20 version 2.0.11
Update to 2.6.4.

Some other fixes not associated with reported bugs were accomplished:

    Add business lot scrubbing to Check & Repair->All/This transaction(s).
    Add context to generic translatable string. This was suggested in
    	Bug 671615 by JÃ©rÃ´me Rapinat.
    Add scrub function to reduce the amount of lot links used. Only lot links
    	between two or more document lots must remain. All lot links between
	document and payment lots can be scrubbed.
    Add some date format checking and make sure generated dates are the correct
    	user selected format, not always locale format.
    Allow the ability to skip rows when importing transactions.
    Always use the price we display to calculate the current value of an
    	account.
    Better period totals formatting in Invoices.
    CSV Export: factor out function to generate regular expression.
    CSV Import transform macro into function.
    Convert ISO-8859-1 account chart templates to UTF-8.
    Correct txf output to use a minus sign, rather than parenthesis.
    Fix document type dispay for credit notes on owner report.
    Fix test-backend-dbi segfault with libdbi-0.9.0.
    Handle the case of scrubbing a lot link between two non-document lots.
    Make scrub in lot viewer scrub business lots using the new scrub functions.
    Move account type checking functions into the engine.
    Prevent older gnucash versions from opening a data file if previously
    	unhandled kvps are used.
    Python bindings. Add function gncVendorNextID, complementary to
        gncCustomerNextID.
    Re-enable loading and saving gnucashdotdir/accelerator-home on OSX.
    Refactor OS-specific ifdef to reduce code duplication, which results
        in reduced risk on typos in either branch
    Refactor get_pay_split into gncOwnerFindOffsettingSplit. In this form it
        can be used both for scrubbing lot links and for adding new payments
    Refactor gncOwnerReduceSplitTo out of reduce_biggest_split. It can now be
        used both for scrubbing and when applying payments
    Refactor gnc_doc_doc_link into gncOwnerSetLotLinkMemo and move it. It can
        now be used both for scrubbing and when applying payments
    Refactor scrub_doc_pay_link into scrub_other_link and make it more generic.
        It can now be used both to:
        * move a payment to a document lot (its original use case)
        * move a refund to a payment lot or the other way around
    Relax requirements for booleans in invoice line, accepting 'y' as well as
        'yes', 't' as well as 'true'.
    Replace C++ reserved words for future compatibility with C++.
    Rework assistant csv import regex code to eliminate the mandatory dummy
        field.
    Rewrite invoice payment logic to fix lot link proliferation.
    SQL: Save commodity namespace changes from template.
    Set default currency for French account chart templates.
    Tweak the get_pay_split function to prefer the best possible match.
    Use libsecret if available since gnome-keyring has been deprecated.
    Use more significant digits for SX function returns.
    Use same default setting for quotes in csv import and export.
    Widen the scope of the subsplit merge scrub function. When used in a
        strict sense it will only merge splits that are marked as subsplits
	of each other. In relaxed mode it will merge any split two splits
	that are both in the same lot and the same transaction.
    double_to_gnc_numeric: Return overflow error immediately on invalid input.
    Ensure that the root account is saved to the SQL backend.
