Remove various calls to SetCapacity() that fall into various misuse categories:
1) Mistakenly believing that the caller should advice the string about zero
terminator.
2) Cases where a single append does the right computation on its own.
3) Calling SetCapacity() with a constant when the string is self-allocated
and could be an nsAuto[C]StringN and the string doesn't get passed on
in a way that could benefit from a heap-allocated buffer.
4) Calling SetCapacity() before assigning a shared buffer to the string.
5) Calling SetCapacity() before calling a function that will either calls
SetLength() anyway or calls Adopt().

...down. The remedy to prevent the crash is to exit the loop when the
mShutdown flag is set. This does not attempt to address the underlying cause
of why the request continues to be pending, although this is also a concern.
Files changed:
netwerk/base/ProxyAutoConfig.cpp - expanded lambda containing logic of when
to stop waiting for the request to complete to include a check to the mShutdown
flag. Also logged a warning if the loop is exited because of mShutdown.

This patch addresses an issue with Firefox's proxy detection on networks which
do not have their a proxy auto-configuration (PAC) file hosted at
http://wpad/wpad.dat, and instead make use of DHCP option 252 for broadcasting
the address of the PAC file. See https://findproxyforurl.com/wpad-introduction/
for an introduction to the protocol.
Prior to this patch, proxy auto-detect missed out the DHCP query stage, and just
looked for a PAC file at http://wpad/wpad.dat
This patch only addresses the issue for Firefox on Windows, although it defines a
DHCP client interface which could be implemented on other platforms.
The high-level components of this patch are:
* nsIDHCPClient.idl - this is an interface which has been defined for querying the
DHCP server.
* nsPACMan.cpp - where previously when the PAC URL was simply set to a constant of
http://wpad/wpad.dat, it now dispatches an asynchronous command to the proxy
thread. The class ExecutePACThreadAction has been augmented to include an
instruction to 'ConfigureWPAD' (Configure Web-proxy auto-detect), and a new class,
'ConfigureWPADComplete' has been created to relay the result (the URL of the PAC
file) back to the nsPACMan object.
* nsProtocolProxyService.cpp
Minor changes to reflect the fact that the PAC URL not being set does not always
mean there is no PAC to be used; instead it could be in the process of being
detected.
* TestPACMan.cpp
This is a new file, and tests only the DHCP auto-detect functionality.
Some tests use multiple threads, as they test the non-blocking proxy detection.
* DHCPUtils.cpp
A class containing the main logic for querying DHCP.
* WindowsNetworkFunctionsWrapper.cpp
A very thin wrapper around the Windows API calls needed by DHCPUtils.
This class was introduced so it could be mocked out in tests.
* nsWindowsDHCPClient.cpp
* An implementation of the interface defined in nsIDHCPClient.idl. Fairly thin:
most logic is implemented in DHCPUtils.
* TestDHCPUtils.cpp
Tests for DHCPUtils and nsWindowsDHCPClient

In the PAC Javascript isInNet function validate the IP address pattern and
subnet mask before using them, using the same regular expression used to
validate the host input, and return false if the values are invalid.

This function is arguably nicer than calling NS_ProcessNextEvent
manually, is slightly more efficient, and will enable better auditing
for NS_ProcessNextEvent when we do Quantum DOM scheduling changes.
