This is a rather mechanical refactor that uses references (&) rather than pointers (*) for parameters that are not permitted to ever be given null arguments. In effect, the onus for checking null pointers is shifted from the callee to the caller. The & type annotation makes it clear that the callee is not prepared to deal with a null pointer.
These commands invariably return true. This is more than a tad confusing to a new reader of the code. Refactor them to return void. Remove a few pieces of dead code that would log something if they ever returned false.
Breaking at the start of the request, end of the request, or end of PSP has been broken for a while. Giving these events a site with the proper URL in them ensures that the rest of the original logic to match and stop on these breakpoints works again. Also updated the help for the breakpoint cmd using the old text from the reference, which seemed reasonable.
I was learning from @jdelong and he said that you should use
double quotes for local includes and angle brackets for library
includes. I asked why our code was the way it was, and he said he wanted
to clean it up. I beat him to it :)

Set the stopped flag for the debugger proxy when it receives a quit command, so that the proxy exits a bit quicker and cleaner. Add a timeout to the cleanup quite of test_debugger, so that it does not hang when a test goes wrong. Add some more tracing.
Added comments to every method in cmd_breakpoint.cpp. Also renamed some methods to make their intent more obvious. Moved a few implementation methods from the public to protected space.
The specification string following a break command was parsed by means of ad-hoc string splitting and sub string finding. This scheme cannot deal with namespaces and class names that contain : (such as xhp classes). There is now a proper parser for break point specifications. Also, xhp class names are mangled before putting them in the BreakPointInfo structure, otherwise breakpoints qualified with xhp classes will not be hit. The syntax for namespaces has been changed to fit the language and if present namespaces are used to mangle function and class names, so that they match the names produced by the regular parser.
Removed the litstr overloads of Array::rvalAt, rvalAtRef, lval,
lvalPtr, lvalAt, and set. The main one left to do is operator[].
Fixed a bug in f_get_html_translation_table() where we were copying
the null terminator of what should be a one-character string, thus
creating a two-character string with s[1] == 0. (cc @jdelong)
In class Extension, store a String for the name instead of
const char*. cc @sgolemon
I found myself getting confused, thinking that proxy->send(cmd) sends a command to the proxy, when in fact it causes the proxy to send the command to the client. These are now named sendToClient, sendToServer and recvFromServer so that future readers (including my future self) will not make this mistake again.
Add a lot of comments to the debugger based on my current understanding of it. These may change in the future as we learn more, but they're helpful right now.
Also moved a few small things around in the code to clarify their purpose or scope. I.e., making a few things private, renaming a few functions, etc. No real logic changes, though. Also minor dead code removal. Also a few lint errors.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
