* connect.c (fd_read, fd_peek): Let implementation take care about timeout.
* gnutls.c (_do_handshake, _do_reauth, wgnutls_read_timeout): Fix support for interactive timeout.
* gnutls.c (wgnutls_peek): Let wgnutls_read_timeout() take care about timeout.
* openssl.c (openssl_read_peek): Fix 0 (-1) timeout.
* retr.c (fd_read_body): Avoid wrong 'interactive timeout'.
Add new implementation for openssl_read, openssl_peek
ssl_connect_with_timeout (openssl). Thats allow continue
read after ETIMEDOUT (if timeout < opt.read_timeout)
without 'Retrying', and do not create thread (under MSWin)
for every read. Old implementation, (with fix for 'timeout')
avaible for build with: -DOPENSSL_RUN_WITHTIMEOUT
Add timeout for transport_implementation {reader,peeker};
* src/init.c (cmd_time): Add check for negative value.
* src/connect.h (transport_implementation {reader,peeker}): Change function prototype.
* src/connect.c (select_fd_nb): New function, aviod conversion to blocked under MSWin.
* src/gnutls.c
(gnutls_read): Fix: using timeout, seting ETIMEDOUT, conversion to blocked.
(gnutls_peek): Likewise.
(wgnutls_errstr): Add errmsg for ETIMEDOUT.
(_do_handshake) (_do_reauth): Fix conversion to blocked.
* src/openssl.c:
Add new implementation for openssl_read, openssl_peek, ssl_connect_with_timeout.
(init_prng): when option --random-file given warn user if RAND_load_file() fail.
* src/connect.c (connect_to_ip): Use xfree() instead of idn2_free()
* src/host.c (lookup_host): Use xfree() instead of idn2_free()
* src/iri.h: Do not include idn2.h
* src/url.c (url_free): Use xfree() instead of idn2_free()
* src/url.h (struct url): Remove 'idn_allocated' from struct

* src/connect.c: check that the fd is not bigger than FD_SETSIZE
before using FD_SET. An fd_set cannot hold fds bigger than
FD_SETSIZE, causing out-of-bounds write to a buffer on the stack.

* .travis.yml: Install libidn2-dev instead libidn11-dev.
* bootstrap.conf: Add modules libunistring-optional, unistr/base,
unicase/tolower.
* configure.ac: Check for libidn2.
* src/Makefile.am: Add $(LTLIBUNISTRING) to LDADD.
* tests/Makefile.am: Set LDADD similar to LDADD in src/Makefile.am
* src/connect.c: Use libidn2 code instead of libidn.
* src/host.c: Likewise.
* src/iri.c: Likewise.
* src/iri.h: Likewise.
* src/options.h: Likewise.
* src/url.c: Likewise.
* src/url.h: Likewise.
* src/log.c: Fix C99 comment.
IDN2003 should not be used any more due to security concerns.
We use libunistring (resp. the unicode code from gnulib) for
lowercasing UTF-8 before we give data to libidn2.
TR#46 is missing, no support in libidn2 nor in libunistring.
* src/connect.c (connect_to_ip): Check return value of setsockopt.
* src/ftp.c (ftp_retrieve_list): Check return value of chmod.
* src/http.c (digest_authentication_encode): Cleanup code.
* src/init.c (setval_internal): Explicitely check comind range.
* src/main.c (main): Explicitely check optarg.
* src/retr.c (retr_rate): Use snprintf instead sprintf,
(retrieve_from_file): More verbose error message,
(rotate_backups): Use snprintf instead sprintf, check return
value of rename().
* src/url.c (mkalldirs): Check return value of unlink().
* src/utils.c (strdupdelim): Explicitely check beg and end for NULL,
(merge_vecs): Fix sizeof argument to char *,
(stable_sort): Use malloc instead of alloca.
xfree() might crash on libidn memory on Windows.
From 'man idn_free':
"Under Windows, different parts of the same application may use different
heap memory, and then it is important to deallocate memory allocated within
the same module that allocated it. This function makes that possible."
