Yusuke Sato 07447544ad Rename ZipEntryName to ZipString
since the struct is now used for other purposes. Also add some
comparator functions to the struct to simplify zip_archive.cc.

This is a follow-up CL for f1d3d3b247.

Yusuke Sato f1d3d3b247 Add |optional_suffix| to StartIteration()
so that PackageManagerService can iterate over files with a
specific file extension like ".so".

Badhri Jagan Sridharan a68d0d1fe4 libziparchive: fix fallocate failures
The objective of fallocate call seems to be to
make sure that we have enough enough space left
in the disk to house the uncompressed file.
But, fallocate is only supported in the following
file systems:
btrfs, ext4, ocfs2, and xfs

Return error only when fallocate fails due to
lack of space. The immediate ftruncate call is
going to take of the majority of other errors.

Narayan Kamath e97e66ea7c Use base::WriteFully in zip_archive.
We're already linking against libbase but we'll have to add
a libbase dependency to every target that includes libziparchive
as a STATIC_LIBRARY dependency, given that there's no way to
express that what we want (except by adding a LOCAL_WHOLE_STATIC_LIBRARY
dependency on libbase to libziparchive but that seems bad too)

Narayan Kamath f899bd534b Avoid mapping output to memory while writing to a file.
It's unnecessary, and causes issues when the uncompressed
output is large.

Łukasz Szymczyk e1d5a6aa5c Reserve space on disk using fallocate
There were crashes when android failed to extract
zip archives due to out of free space on disk, with stacks like:

  #00 pc 00000000000156b0 /system/lib64/libc.so (memcpy+176)
  #01 pc 000000000002e5b8 /system/lib64/libandroidfw.so
  #02 pc 000000000002f488 /system/lib64/libandroidfw.so (ExtractToMemory+328)
  #03 pc 000000000002f5c8 /system/lib64/libandroidfw.so (ExtractEntryToFile+268)
  #04 pc 00000000000287d8 /system/lib64/libandroidfw.so (android::ZipFileRO::\
  uncompressEntry(void*, int) const+12)

Space for the file is now allocated using fallocate rather than
ftruncate, since ftruncate dont actually reserve space on disk. When writes
to the mmaped pointer fails to be realized due to out of space SIGBUS
is the result. With this change we make sure that there is space available
before mmaping the pointer.

Narayan Kamath 6832a7a4e0 Remove useless refCounting from FileMap.
Nobody ever called acquire() so release() was always
equivalent to delete. Just use delete instead so that
people can use unique_ptr directly (or shared_ptr if
they really want refcounts).

Narayan Kamath 48953a1b8f Fix entry handling for 0 length entries.
Two minor issues were fixed:
- The offset to entry data can be the same as the
  central directory offset when the last entry in the
  file has length 0 and is stored (not deflated). Fix
  a check that disallowed this. We already have a strict
  check that entry data must end before the central directory,
  so we're covered.
- We would attempt to map a segment of length 0 when writing
  an entry whose length is 0. We should just return early in
  this case.
