On our x86 Android toolchain, getpwuid_r is implemented but the header
is missing:

 netrc.c:81:7: error: implicit declaration of function 'getpwuid_r' [-Werror=implicit-function-declaration]

Unfortunately, the function is used in curl_ntlm_wb.c, too, so I moved
the prototype to curl_setup.h.

Adds CURLOPT_DISALLOW_USERNAME_IN_URL and --disallow-username-in-url. Makes
libcurl reject URLs with a username in them.

* enable it in `src/Makefile.m32`
* enable it in `winbuild/MakefileBuild.vc` if a custom manifest is
  _not_ enabled via the existing `EMBED_MANIFEST` option
* enable it for all Windows CMake builds (also disable the built-in
  minimal manifest, added by CMake by default.)

For other build systems, add the `-DCURL_EMBED_MANIFEST` option to
the list of RC (Resource Compiler) flags to enable the manifest
included in `src/curl.rc`. This may require to disable whatever
automatic or other means in which way another manifest is added to
`curl.exe`.

Notice that Borland C doesn't support this method due to a
long-pending resource compiler bug. Watcom C may also not handle
it correctly when the `-zm` `wrc` option is used (this option may
be unnecessary though) and regardless of options in certain earlier
revisions of the 2.0 beta version.

The automake default ar flags are 'cru', but the 'u' flag in there
causes warnings on many modern Linux distros. Removing 'u' may have a
minor performance impact on older distros but should not cause harm.

This was added earlier but appears to have been removed accidentally.

AFAICT this is very much still an issue.

I say "accidentally" because the text seems to have harmlessly snuck
into [1] (which makes no mention of it).  [1] was later reverted for
unspecified reasons in [2], presumably because the mentioned issue was
fixed or invalid.

A non-escaped bracket ([) is for a character group - as documented. It
will *not* match an individual bracket anymore. Test case 1307 updated
accordingly to match.

Problem detected by OSS-Fuzz, although this fix is probably not a final
fix for the notorious timeout issues.

The latest psl is cached in the multi or share handle. It is refreshed

The ssh2 pkg-config file could contain the following lines when build
with a static version of mbedtls:
   Libs: -L${libdir} -lssh2 /xxx/libmbedcrypto.a
   Libs.private: /xxx/libmbedcrypto.a

This static mbedtls library must be used to correctly detect ssh2
support and this library must be copied in libcurl.pc otherwise
compilation of any application (such as upmpdcli) with libcurl will fail
when trying to found mbedtls functions included in libssh2.  So, replace
pkg-config --libs-only-l by pkg-config --libs.

Bug: #2609
Signed-off-by: Bernhard Walle <bernhard@bwalle.de>

--data, --form, and --ntlm were declared to be mutually exclusive with
non-existing options. --data and --form referred to --upload (which is
short for --upload-file and therefore did work, so this one was merely
a bit confusing), --ntlm referred to --negotiated instead of --negotiate.

follow-up to mistake in 6876ccf9

OpenSSL has supported --cacert for ages, always accepting LF-only line
endings ("Unix line endings") as well as CR/LF line endings ("Windows
line endings").

When we introduced support for --cacert also with Secure Channel (or in
cURL speak: "WinSSL"), we did not take care to support CR/LF line
endings, too, even if we are much more likely to receive input in that
form when using Windows.

Let's fix that.

Happily, CryptQueryObject(), the function we use to parse the ca-bundle,
accepts CR/LF input already, and the trailing LF before the END
CERTIFICATE marker catches naturally any CR/LF line ending, too. So all
we need to care about is the BEGIN CERTIFICATE marker. We do not
actually need to verify here that the line ending is CR/LF. Just
checking for a CR or an LF is really plenty enough.
