segments.py: fix TLS checks in section_in_segment() (#275)
While the comment in section_in_segment() suggests that the
logic follows the logic inside ELF_SECTION_IN_SEGMENT_1 with
the strict parameter set, all of the checks in the binutils
macro are written so that they must succeed for the section
to be contained in the current segment. In our implementation,
however, the checks were not properly negated.
This showed in the case of .tdata and .tbss which did not
appear in the section to segment mapping (these sections are
found in glibc, for example).
Fix it up by aligning the logic more closely to the binutils
macro by implementing the same logic and returning False only
if the checks fail. Additionally, introduce the third check
from the upstream binutils which checks the combination of
SHT_ALLOC sections and PT_LOAD-like segments.
Furthermore, in the original check, the PT_GNU_RELRO type was
misspelled with a 0 (zero) instead of an O so this check
could never have worked.

Improve symbol table handling in DynamicSegment (#219)
dynamic: parse DT_{GNU_}HASH for number of symbols
In ultra-stripped binaries we can find the symbol table by
parsing the dynamic segment and using the pointer in the
DT_SYMTAB tag as the base address. However, we don't know
anything about the number of symbols in the symbol table.
Earlier, this code relied on finding the closest pointer
value bigger than the base address of the symbol table. In
PIE executables and shared libraries however this method
could break as the pointer value for DT_SYMTAB is in the same
range as things like DT_RELASZ or DT_STRSZ, leading to a too
small number of symbols returned by iter_symbols().
The crashpad project has implemented a different strategy to
find the number of symbols: parsing the symbol lookup hash
tables (see [0]) as every symbol must have a corresponding
entry in the hash table. This commit implements this
behaviour for DynamicSegment, leaving the old code as a
backup if neither DT_HASH or DT_GNU_HASH tags have been
found.
For DT_HASH type tables, it is quite easy as the header
already contains the number of entries. For DT_GNU_HASH
things are a bit more complicated as we need to work forward
from the highest symbol referenced in the header (a good
explanation of the format can be found at [1]).

* dynamic: provide more functions for symbol access
So far, the DynamicSegment only provided a method to iterate
over all symbols but for some use cases it might be useful to
use the recovered symbol table more like a normal
SymbolTableSection.
To this end, provide get_symbol(index) to fetch a symbol by
its index, num_symbols() to get the total number of symbols
and get_symbol_by_name(name) to look for a list of symbols
with a given name.

This is due to the specification of LC_ALL as simply `en_US` without an encoding. Python 3.x seems to be fine with this, but Python 2.7 barfs. As a fix, setting `LC_ALL` to `en_US.utf-8` (including an explicit encoding spec) works.

* Add EF_MIPS_PIC for E_FLAGS for statically linked MIPS-I executable produced by MUSL
pyelftools picked up CPIC but not PIC
binutils readelf says:
Flags: 0x1007, noreorder, pic, cpic, o32, mips1
pyelftools said (before this change):
Flags: 0x1007, noreorder, cpic, o32, mips1
Reproduce with the binary available at:
https://github.com/mzpqnxow/embedded-toolkit/blob/master/prebuilt_static_bins/gdbserver/gdbserver-6.8-mips-i-rtl819x-lexra
* Fix order of fix, was "cpic, pic" needs to be "pic, cpic", reordered the if statement to address this
* - Improve reporting on MIPS flags, fix many inconsistencies with GNU binutils
- Fix `desrciption` typo that raises fatal exception when encountering an unknown ABI
- Add E_FLAGS_MASKS constants to simplify ABI logic
* Add masks for E_FLAGS to simplify ABI logic

Compressed sections (#152)
* Add constants, enums and structs for compressed section
* ELFStructs: update comments for new section numbers in Oracle docs
* Make the ELFFile's stream/structs available to all Section instances
This harmonizes the signature of Section constructors. Besides, structs
will be required to read compressed sections.
* ELFFile._read_dwarf_section: use Section.data to read the section
An upcoming change will add compressed sections handling. In this
context, the DWARF must be parsed from the decompressed data, so reading
the ELFFile stream will be wrong.
