92b29e1925 libsnapshot: Add a test case for recent decompress regression. 
The attached test data is a 4096 length byte run that gz compresses to
exactly 4096 bytes. This exposes an edge case in CowReader::ReadData
with v2 snapshot files.

84e41ca0e2 run-as: remove a special case. 
This is a change for some system apps that have /data/user_de/0/ in the
package list, but it's easier to reason about and more consistent to
always go down the same path.

c2ce084889 libsnapshot: implement resume buffer 
Add resume space to cow v3. Resume buffer goes after header and scratch
space, and is currently set to contain 4 resume points. When AddLabel is
called, the oldest label is replaced with newest one.

Parser will parse up until the last resumable op from a given label.

Timeouts in tombstoned.cpp and intercept_manager.cpp are scaled
by HwTimeoutMultiplier, but the timeouts in debuggerd_test.cpp
are not, which means the CrasherTest#intercept_timeout test will
fail for any platform that has a high enough HwTimeoutMultiplier.

bfc115311e run-as: reduce the scope of changed egid. 
There's no bug here that I can see, but having a larger than necessary
scope just seems like a bad idea in case anyone adds anything later.

Also switch to modern struct initialization syntax.

e363841e75 libsnapshot: Add single threaded compression to v3 writer 
Add compression path back into Cow operations. Main change is that the
compression algorithm is stored in the header instead of each individaul
op. Have the writer_v3 set this algorithm when parsing options.

There looks to be a lot of code we'll be able to factor out into the
base class, but we can leave that to a later CL.
