* remove conflicting receive function

Co-authored-by: smartcontracts <kelvinfichter@gmail.com>

* fix Warning: Unused function parameter. Remove or comment out the variable name to silence this warning.

* fix: shadows another variable error

* fix: Warning: Visibility for constructor is ignored.

* fix: unused local variable warning

* fix: Warning: Function state mutability can be restricted to pure

* Warning: Return value of low-level calls not used.

* fix: Warning: Unnamed return variable can remain unassigned.

* fix: final Warning: Visibility for constructor is ignored. If you want the contract to be non-deployable, making it abstract is sufficient

* implement comments

* fix: change return to address(0) to silence compiler

* perf: reset xDomainMessageSender to default value after external call

Fixes https://github.com/ethereum-optimism/contracts/issues/309

We also set `xDomainMessageSender in the `initialize` function in L1, and in the L2 constructor.

* test: ensure that xDomainMessageSender is always 0xdead before/after calls

* chore: use parent constructor for initializing the L2 xdomain sender

* fix: require that the xDomainSender is not the default value
