Fixes a hang of the staging import tool when it
attempts to process a MARC21 record that claims
that it's UTF-8 when it is not. The staging import
will now attempt to fix the character encoding of such
records.
Also added a FIXME to bulkmarcimport.pl, which because
of its use of MARC::Batch will skip over such records -
better than the original hang of the staging import, but
worse than the staging import's new ability to fix such
records.

This patch fix the funciton SetMarcUnicodeFlag for UNIMARC support, now the function will fix the length of the field, and set encoding as "50 " instead of "5050".

This has bearing on bugs 2905, 2665, 2514 and other "wide character" crashes
related to diacritics and Unicode. This should help open the door for reliable
input of diacriticals via acquisitions.
MARC21_utf8_flag_fix.pl diagnoses and fixes existing problems with MARC data
affected by the bug.
Adding SetMarcUnicodeFlag to TransformKohaToMarc prevents the bug from corrupting
further data.

A script like bulkmarkimport.pl spends most of the time
in C4::Charset::MarcToUTF8Record function, and
specifically in C4::Charset::char_decode5426
just initializing a hash. This patch moves this
hash outside function to avoid its initializing
each time the functon is called.
A test on a specific conversion script shows me
that performances were improved from 23s to 8s.

Because of a bug in MARC::Charset 0.98, if a string to convert from
MARC-8 to UTF-8 has (a) one or more diacritics that (b) are only in character positions
128 to 255 inclusive, the resulting converted string is not in
UTF-8, but the legacy 8-bit encoding (e.g., ISO-8859-1). As a result,
when such a record is converted to XML using ->as_xml_record(), the resulting
XML can be truncated at the offending character. An example of such a record
is one that has a price in Briish pounds in the 260$c but no other diacritics.

Added invocations of StripNonXmlChars to uses
of new_from_xml() that involve records
saved to Koha fields via MARC::Record->as_xml();
for batch jobs that work on MARC XML files
coming from external sources, StripNonXmlChars
should not necessarily be used, as it may
be better to reject a file or record if it
contains that kind of encoding error.

* IsStringUTF8ish - determine if scalar contains a string in UTF8
* MarcToUTF8Record - convert MARC blob or MARC::Record to UTF8
* SetMarcUnicodeFlag - set appropriate MARC21 or UNIMARC field to
indicate that record is in UTF-8.
Design points of this module include:
* No dependencies on other C4 modules, making it easier to add
more test cases
* All character conversion code in one place
* Single entry point for doing a character conversion on a
MARC record
* Capture of errors and warnings produced by Text::Iconv
and MARC::Charset
* Start of support for guessing the source character set of
a MARC record.
Several functions were moved from other scripts
or modules to C4::Charset:
* C4::Koha->FixEncoding (expanded and renamed
MarcToUTF8Record)
* C4::Koha->char_decode5426
* fMARC8ToUTF8 from bulkmarcimport.pl (renamed
_marc_marc8_to_utf8)
Several batch jobs were adjusted to use MarcToUTF8Record instead of
FixEncoding.

A new C4::Charset module (tentative name) has been created to guess the
charset of a piece of HTML markup. The CGI programs will be modified to use
this module as they are encountered during translation.
