Add CryptoNative_X509UpRef

Use X509UpRef instead of X509Duplicate

X509Duplicate copies the certificate data into new memory, but none of the
callers needed copy semantics, just ensuring that the native components
which also are using the same memory don't unexpectedly free the object.

Protection from early/double-free is what the native reference count field is
for, so use UpRef instead of Duplicate.

Since we are currently targeting OpenSSL 1.0.x X509Upref adds to
references directly, X509_up_ref does not exist in the 1.0.x ABI.

Microbenchmark:
Cloning a certificate 1000 times by cert.Handle, measuring maximum resident set:
X509Duplicate (before): 48213 +/- 1501KB
X509UpRef (after): 39208 +/- 1021KB
Memory reduction: 9005 +/- 1816KB

Improve behavior of TcpClient Dispose concurrent with ConnectAsync

TcpClient.Dispose is not meant to be used concurrently with other operations on the instance, but some code does do so as a way to provide a cancellation mechanism.  There are two easily hit issues with this:
1. On Unix, the ConnectAsync operation doesn't publish the actual Socket on which a connection was made until after the connection is established, as it needs to use temporary sockets to try each potential target address, and publishing it before connecting could end up publishing a Socket that won't end up being the actual one used.  As such, if a Dispose occurs during the ConnectAsync operation, it won't end up disposing the socket being used to make the connection, such that the connection won't be canceled.
2. On all platforms, Dispose nulls out the client socket field.  When the connection then subsequently completes, it hits a NullReferenceException while trying to dereference that field.

This commit addresses both issues:
a. When the client is disposed, on Unix we cancel a CancellationTokenSource, and each Socket we create is registered with that source to dispose the socket.  That way, we dispose of each socket even if it hasn't been published onto the instance yet.
b. We grab the Socket from the field and check for null prior to dereferencing it.

Define _BSD_SOURCE macro for getline on FreeBSD

According to manpage:

https://www.freebsd.org/cgi/man.cgi?query=getline&apropos=0&sektion=0&manpath=FreeBSD+8.2-RELEASE&format=html

FreeBSD requires either `_WITH_GETLINE`, `_BSD_SOURCE` or `_GNU_SOURCE`
defined to make `getline` available via `<stdio.h>`.

By adding a definition in CMake is the cleanest way as otherwise we get:

> macro name is a reserved identifier

and muting it with `pragma` will be a messier solution
(e.g. dotnet/corefx@ba88726).

Fix HttpWebResponse.ContentType when response has invalid headers

The HttpWebResponse.ContentType property is supposed to return a string value with the response's `Content-Type` header value. Even if the response header is considered non-conformant with RFC7231, the value is returned as-is as received on the wire.

In .NET Core, HttpWebRequest/HttpWebResponse is implemented as a wrapper around HttpClient. HttpClient has a strongly-typed model for headers. The current implementation of HttpWebResponse.ContentType was trying to use the strongly typed header from HttpClient. In cases where the header was malformed, it was returning empty string. This was a difference in behavior from .NET Framework.

The fix is to use TryGetValues() to retrieve the raw response header value for the 'Content-Type' header. This will result in compatible behavior with .NET Framework.

Fixes dotnet/corefx#9433.

Fail init-tools atomically

Before this change, a failure fairly early in the `init-tools.sh` process could result in subsequent attempts being short-circuited.

This introduces a marker file that is only written at the very end of the script, so that a `dotnet restore` or `init-tools.sh`-from-package failure can be retried immediately.
