Instead of defaulting to OpenSSL, allow selection of package to use
through a choice in libcurl's config. The default will be to select the
first enabled TLS provider in the same preference order as is used now,
i.e. no change from current behavior.
Some of the alternative libraries have advantages over OpenSSL in
certain areas.
For example, gnutls has vastly superior PKCS11 support. One can use
client TLS private keys by supplying a PKCS11 URI instead of a private
key file name. The TLS server cert trust store can be a PKCS11 URI,
e.g. configure libcurl with a ca-bundle of "pkcs11:model=p11-kit-trust".
Now server certs can be stored in a software and/or hardware HSM(s).
This doesn't work with OpenSSL.
However, some software only supports OpenSSL for TLS or other crypto
functions. So it might be necessary to enable OpenSSL for that reason.

[Peter: add BR2_PACKAGE_LIBCURL_TLS_SUPPORT and use it to hide choice &
comment, explitly pass --without-foo if option is not enabled,
only do .pc fixup if BR2_PACKAGE_LIBCURL_OPENSSL is enabled]

The check-package script when ran gives warnings on text wrapping
on all of these Config files. This patch cleans up all warnings
related to the text wrapping for the Config files starting with
lib in the package directory.
The appropriate indentation is: <tab><2 spaces><62 chars>
See http://nightly.buildroot.org/#writing-rules-config-in for more

This patch enables a config to set --enable-verbose during the
configuration of libcurl. The option is triggered by setting
BR2_PACKAGE_LIBCURL_VERBOSE.

In the Config.in file of package foo, it often happens that there are other
symbols besides BR2_PACKAGE_FOO. Typically, these symbols only make sense
when foo itself is enabled. There are two ways to express this: with
depends on BR2_PACKAGE_FOO
in each extra symbol, or with
if BR2_PACKAGE_FOO
...
endif
around the entire set of extra symbols.
The if/endif approach avoids the repetition of 'depends on' statements on
multiple symbols, so this is clearly preferred. But even when there is only
one extra symbol, if/endif is a more logical choice:
- it is future-proof for when extra symbols are added
- it allows to have just one strategy instead of two (less confusion)
This patch modifies the Config.in files accordingly.

In 9229b82d63 ('libcurl: needs MMU'),
the libcurl package was disabled on non-MMU systems, due to the usage
of the fork() function in the library.
However, a deeper inspection reveals that fork() is only used in the
implementation of NTLM, an obscure, undocumented, Microsoft specific
authentication method that apparently isn't common anymore. See
http://curl.haxx.se/docs/manpage.html#--ntlm.
Therefore, this commit re-enables libcurl on non-MMU systems by
explicitly disabling the NTLM support. If someone ever needs NTLM
support in Buildroot's libcurl package, it will always be time to add
a libcurl sub-option to enable it.
