toolchain: add option to copy the gconv libraries

The gconv libraries are used to translate between different character sets
('charsets', even 'csets' sometimes). Some packages need them to present
text to the user (eg. XBMC Gotham).

In (e)glibc they are implemented by the internal implemenation of iconv,
called gconv, and are provided as dlopen-able libraries.

Note that some gconv modules need extra libraries (shared by more than
one gconv module), so we must, when adding a subset of modules, scan the
installed modules in search of the missing libraries.

[Thomas: add general explanation in expunge-gconv-modules and fix
coding style.]

icu: add an option to add a custom data library file

[Thomas:
 - use one single BR2_PACKAGE_ICU_CUSTOM_DATA_PATH string option
   instead of a boolean option + a string option, which always causes
   a lot of issues with random configurations that enable the boolean
   option, but do not provide a valid value for the string option.
 - enclose the definition of ICU_COPY_CUSTOM_DATA into the condition.]

package/lftp: inverse the openssl/gnutls selection

openssl is more widely used than gnutls. Other packages prefer openssl
over gnutls and would like to do the select in the opposite direction.

So switch lftp to use openssl by default, and only revert to using
gnutls if explicitly selected by the user.

flickcurl: remove ca-certificates as a build dependency

ca-certificates is a runtime dependency only, so selecting it in the
Config.in file is sufficient, adding it to FLICKCURL_DEPENDENCIES is
not useful.

flickcurl: adjust openssl dependency

flickcurl does not specifically need openssl: it needs libcurl to have
crypto support to access https:// URLs. So, instead of depending on
openssl in FLICKCURL_DEPENDENCIES, this commit simply leaves it to the
Config.in file to select either OpenSSL, gnutls or libnss to make sure
libcurl will use one of these libraries.
